Ultra fast, ultra low energy transistors in Electronic and Optical Nanosystems, 2014 Foresight Technical Conference: Integration

Posted by candice on December 8th, 2013

Ultra fast, ultra low energy transistors in Electronic and Optical Nanosystems

Dr. Reza Arghavani is the Managing Director of Technology for LAM Research Corporation. He will be speaking on the realization of nanotechnology approaching the atomic scale that underpins the ultra fast, ultra low energy transistors of the 22nm node devices on sale today and the challenges for creating the even more demanding, smaller, faster and lower power devices of the future as we approach the limits of design.

Prior to Lam Research, Dr. Arghavani was the CTO and Co-Founder of Universal Phase, Inc., and was responsible for the realization of a transistor based apparatus to deliver focused microwave energy into a cavity for Energy and SEMI industrial applications. As a Fellow at Applied Materials [one of only three at AMAT], Dr. Arghavani led a team to create a series of stress inducing dielectrics, which are currently in use in high volume manufacturing for both Logic and Non-Volatile Memory applications. This program led to over $800 million revenue in a period of two years.

At Intel Corporation Logic Technology Development, Dr. Arghavani was responsible for three generations of high performance microprocessor gate stack technology. Dr. Arghavani introduced the first High K Atomic Layer Deposition (ALD) into Intel development FABs. This work eventually led to the introduction of High-K / Metal Gates into 45nm INTEL Microprocessors [débuted by Gordon Moore as the biggest change in transistor technology since the late 1960s]. He was also part of the original Intel development team that invented and patented the 3-D Tri-Gate transistor, now in high volume manufacturing for the 22nm node.

2013 conference video: Mechanical Atom Manipulation

Posted by Jim Lewis on December 2nd, 2013

A select set of videos from the 2013 Foresight Technical Conference: Illuminating Atomic Precision, held January 11-13, 2013 in Palo Alto, have been made available on vimeo. Videos have been posted of those presentations for which the speakers have consented. Other presentations contained confidential information and will not be posted.

The 4th speaker in the Atomic Scale Devices session was Philip Moriarty. His talk was titled “Mechanical Atom Manipulation: Towards a Matter Compiler?biography and abstract, video – video length 31:14.

Prof. Moriarty presented his work with the qPlus technique of non-contact AFM of semiconductors, using chemical forces to mechanically move atoms around to structure matter, focusing on the tip of the probe—specifically how to optimize the tip structure, and how to return the tip to a previously known state. He begins with a brief review of how non-contact AFM uses a damped, driven oscillator to measure and manipulate what is happening at the level of single chemical bonds. The tip at the end of the oscillating cantilever measures the frequency shift of the cantilever as it approaches and interacts with the surface, and it maintains a constant amplitude of oscillation by pumping energy into the system. The frequency shift provides information about conservative forces acting on the tip, and the amount of energy pumped in gives a handle on non-conservative, or dissipative, forces. Before diving into the experimental details of his own work, Prof. Moriarty noted that various experimental accomplishments have vindicated Eric Drexler’s assertion that single atom chemistry could be done using purely mechanical force.

The goal of the modular molecular composite nanosystems (MMCNs) path to atomically precise manufacturing is to exploit million-atom-scale DNA frameworks to assemble and coordinate molecular components to build complex functional nanostructures. Last year we cited work in which molecular motor proteins were used to transport synthetic DNA cargos along a 25-nm-diameter protein track composed of microtubules, the networks used to transport molecular cargo in human and other eukaryotic cells. Demonstrating another way in which to use these molecular components for similar purposes, other researchers have now used DNA nanotechnology to organize and control networks for transporting molecular cargo by incorporating molecular motors into different types of functional nanostructures. A hat tip to ScienceDaily for reprinting this Oxford University press release “All aboard the nanotrain network“:

Tiny self-assembling transport networks, powered by nano-scale motors and controlled by DNA, have been developed by scientists at Oxford University and Warwick University.

The system can construct its own network of tracks spanning tens of micrometres in length, transport cargo across the network and even dismantle the tracks.

The work is published in Nature Nanotechnology [abstract] ….

Researchers were inspired by the melanophore, used by fish cells to control their colour. Tracks in the network all come from a central point, like the spokes of a bicycle wheel. Motor proteins transport pigment around the network, either concentrating it in the centre or spreading it throughout the network. Concentrating pigment in the centre makes the cells lighter, as the surrounding space is left empty and transparent.

H-S Philip Wong discusses Carbon Nanotube Devices at 2014 Foresight Technical Conference: Integration

Early Registration ends 11/25 – Use promo code NANOBLOG for $100 off registration.

In October, Professor Wong along with colleagues at Stanford University published the development of a digital computer which uses carbon nanotubes as transistors. The team was able to integrate 142 carbon nanotube transistors into a multitasking computer programmable through a 20 instruction set. Professor Wong will relate the trials and triumphs in the integration strategy, as well as insight into other strategies for ultra small, high speed low power switching.

To put these accomplishments into perspective we need only look back to 2008 at which time the integration of five carbon nanotubes was cutting edge technology.

Upcoming Book Explores Nanomedical Device and Systems Design

Posted by Jim Lewis on November 21st, 2013

Nanomedical Device and Systems Design: Challenges, Possibilities, Visions Published: November 18, 2013 by CRC Press Content:787 Pages | 223 Illustrations Editor(s):Frank Boehm

Aubrey de Grey (Chairman and Chief Science Officer of the Methuselah Foundation and Editor-in-Chief of the high-impact journal Rejuvenation Research) offers some affirmative comments below, subsequent to a review of the upcoming book: Nanomedical Device and Systems Design: Challenges, Possibilities, Visions (CRC Press/Taylor & Francis)
edited by Frank J. Boehm, which is slated for release on November 25, 2013.

“This book is extraordinarily detailed and comprehensive, and succeeds splendidly as an update to a field previously defined by Freitas’s similarly encyclopedic works. A particularly strong element is the thorough dissection of methods of nanodevice delivery covered in the first section. I am most impressed by the book’s structure. One particularly nice decision was to open up the central section to invited authors, giving the book a level of variety that is otherwise challenging to deliver. The level of detail presented is the main thing I am looking for in such highly speculative engineering design surveys, and it is fantastic here.”

“Robert Freitas defined the field of nanomedicine with his encyclopedic analysis published at the turn of the century. After 15 years, the time is right to provide an updated view, but can Freitas’s comprehensiveness ever be matched? Boehm has shown that it can. As Freitas did, he has risen to the formidable challenge of tackling a hugely speculative area of pioneering technology with a level of thoroughness that should give even the cautious reader a substantial level of confidence that, once the most basic nuts and bolts of molecular manufacturing are available (and progress towards them is already encouraging), their application to some of our greatest needs may rapidly follow.”

Upon his review of the book, Ted Kucklick, author of The Medical Device R&D Handbook, notes that “Nanomedical Device and Systems Design: Challenges, Possibilities, Visions speculates where nanotechnology for medicine might develop in the next 10-20 years, and postulates a number of possibilities for therapeutic applications including artificial blood and neuroprosthetics and posthuman augmentation. Medical futurists may find this book useful in anticipating where these technologies may lead.”

Graphene nanoribbon senses passage of individual bases of DNA

Posted by Jim Lewis on November 19th, 2013

Caption: Many efforts over last decade have been directed towards development of single molecule sequencing based on solid state nanopores. Aleksandra Radenovic and co-workers have made a device composed of a graphene nanoribbon transistor built on top of a solid state nanopore. Direct electrical readout from the graphene transistors is used to detect DNA translocation events. Nanopore, DNA and the graphene nanoribbon are shown in this schematic (which is not to scale). Credit: EPFL

A major contribution of current and near-term nanotechnology to medical advance will be improving DNA sequencing technology to enable fully individualized medical treatment. In an important step toward very rapid DNA sequencing, researchers have used a graphene nanoribbon transistor to sense the movement of a DNA molecule through a nanopore. A hat tip to ScienceDaily for reprinting this public release from the Ecole Polytechnique Fédérale de Lausanne in Switzerland: “Graphene nanoribbons for ‘reading’ DNA“.

… The DNA molecules are diluted in a solution containing ions and are driven by an electric field through a membrane with a nanopore. When the molecule goes through the orifice, it provokes a slight perturbation to the field, detectable not only by the modulations in ionic current but also by concomitant modulation in the graphene transistor current. Based on this information, it is possible to determine whether a DNA molecule has passed through the membrane or not.

This system is based on a method that has been known for over a dozen years. The original technique was not as reliable since it presented a number of shortcomings such as clogging pores and lack of precision, among others. “We thought that we would be able to solve these problems by creating a membrane as thin as possible while maintaining the orifice’s strength”, said Aleksandra Radenovic from the Laboratory of Nanoscale Biology at EPFL. Together with Floriano Traversi, postdoctoral student, and colleagues from the Laboratory of Nanoscale Electronics and Structures, she came across the material that turned out to be both the strongest and most resilient: graphene, which consists of a single layer of carbon molecules. The strips of graphene or nanoribbons used in the experiment were produced at EPFL, thanks to the work carried out at the Center for Micro Nanotechnology (CMI) and the Center for Electron Microscopy (CIME).

Nanoparticle therapy for incurable brain cancer effective in mice

Posted by Jim Lewis on November 15th, 2013

Back in 2009 we cited promising work from Chad Mirkin (winner of the 2002 Foresight Institute Feynman Prize in Nanotechnology in the Experimental category) that covering 13-nanometer gold nanoparticles with siRNA molecules enable the usually unstable and fragile molecules to enter tumor cells in culture and silence the tumor cell gene against which the siRNA molecules were targeted. We now learn that these spherical nucleic acid nanoparticle conjugates show activity in cell culture and in mouse models against an incurable brain cancer called glioblastoma multiforme (GBM). A hat tip to ScienceDaily for reprinting this Northwestern University news release by Megan Fellman “Incurable Brain Cancer Gene Is Silenced: Gene regulation technology increases survival rates in mice with glioblastoma“:

Glioblastoma multiforme (GBM), the brain cancer that killed Sen. Edward Kennedy and kills approximately 13,000 Americans a year, is aggressive and incurable. Now a Northwestern University research team is the first to demonstrate delivery of a drug that turns off a critical gene in this complex cancer, increasing survival rates significantly in animals with the deadly disease.

The novel therapeutic, which is based on nanotechnology, is small and nimble enough to cross the blood-brain barrier and get to where it is needed — the brain tumor. Designed to target a specific cancer-causing gene in cells, the drug simply flips the switch of the troublesome oncogene to “off,” silencing the gene. This knocks out the proteins that keep cancer cells immortal.

In a study of mice, the nontoxic drug was delivered by intravenous injection. In animals with GBM, the survival rate increased nearly 20 percent, and tumor size was reduced three to four fold, as compared to the control group. The results are published today (Oct. 30) in Science Translational Medicine [abstract].

Many different types of nanoparticles have been proposed as improved drug delivery vehicles for nanomedical use, ranging from nanoscale lipid vesicles to atomically precise nucleic acid nanostructures. Together they provide various approaches to solving the many challenges involved in efficiently transporting a drug to the right target. Researchers at McGill University have now modified DNA strands with lipid-like molecules to better hold a cargo of drug molecules. A hat tip to Newswise for reprinting this McGill University news release “DNA ‘cages’ may aid drug delivery“:

Nanoscale “cages” made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, McGill University researchers report in a new study.

The research, published online Sept. 1 in Nature Chemistry [abstract], marks a step toward the use of biological nanostructures to deliver drugs to diseased cells in patients. The findings could also open up new possibilities for designing DNA-based nanomaterials.

“This research is important for drug delivery, but also for fundamental structural biology and nanotechnology,” says McGill Chemistry professor Hanadi Sleiman, who led the research team. …

In their experiments, the McGill researchers first created DNA cubes using short DNA strands, and modified them with lipid-like molecules. The lipids can act like sticky patches that come together and engage in a “handshake” inside the DNA cube, creating a core that can hold cargo such as drug molecules.

Biology is capable of evolving functional mechanical gears

Posted by Jim Lewis on October 16th, 2013

Credit: University of Cambridge

It has long been noted in discussions of atomically precise manufacturing that biological molecular machinery provides an existence proof for manufacturing complex molecular machinery. However, proposals for mature atomically precise manufacturing systems resemble scaled down conventional manufacturing systems, with gears and other rigid components familiar at the macroscale. In contrast biological molecular machine systems comprise floppy molecules interacting via controlled Brownian motion. Is it possible for evolution to develop machines with gears, etc.? Apparently evolution is capable of inventing mechanical gears, albeit at much larger than molecular scale. A hat tip to ScienceDaily for reprinting this news release from the University of Cambridge “Functioning ‘mechanical gears’ seen in nature for the first time“:

Previously believed to be only man-made, a natural example of a functioning gear mechanism has been discovered in a common insect – showing that evolution developed interlocking cogs long before we did.

The juvenile Issus – a plant-hopping insect found in gardens across Europe – has hind-leg joints with curved cog-like strips of opposing ‘teeth’ that intermesh, rotating like mechanical gears to synchronise the animal’s legs when it launches into a jump.

The finding demonstrates that gear mechanisms previously thought to be solely man-made have an evolutionary precedent. Scientists say this is the “first observation of mechanical gearing in a biological structure”.

Through a combination of anatomical analysis and high-speed video capture of normal Issus movements, scientists from the University of Cambridge have been able to reveal these functioning natural gears for the first time. The findings are reported in the latest issue of the journal Science [abstract].

TEDx talk: "Transforming the Material Basis of Civilization"

Posted by Stephanie C on October 14th, 2013

Eric Drexler speaks at TEDx Lisbon

Eric Drexler’s TEDx talk entitled “A Future of Radical Abundance: Transforming the Material Basis of Civilization” is available for viewing on Youtube as well as on Drexler’s blog site.

As described by the Oxford Martin School, where Drexler is a scholar with the Programme on the Impacts of Future Technology:

Dr. Eric Drexler’s talk from TEDx IST Alameda (18 June 2013)

‘A Future of Radical Abundance: Transforming the Material Basis of Civilization’

What if an advanced production technology could enable us to transition to a global economy with zero carbon emissions, and then enable us to undertake the vast task of removing excess carbon from Earth’s atmosphere? What if we could learn to make a broad spectrum of products cleanly, at low cost, and on a global scale? If so, then prospects for the 21st century would be different from today’s expectations.

Eric Drexler’s recent TEDx talk in Lisbon describes the physical basis and historical context of a prospective revolution in the material basis of our civilization: high-throughput atomically precise manufacturing. The level of technology required is visible in the distance today—not close, yet accessible through a series of advances in nanotechnology and the molecular sciences. As global problems intensify, understanding this technological potential has become increasingly urgent. Eric’s TEDx talk surveys this topic and provides a framework for further discussion.

Carbyne: the strongest, stiffest carbon chain

Posted by Stephanie C on October 11th, 2013

Carbyne – a straight line of carbon atoms linked by double bonds or by alternating single and triple bonds — is the next stiff, carbon-based structure with unusual and desirable properties. It has been observed under limited natural and experimental conditions, is expected to be difficult to synthesize and store, and now has been theoretically characterized.

Researchers at Rice University recently published DFT characterizations of carbyne ropes and rods, and overviews of the findings and prospects are reprinted at

According to the portrait drawn from calculations by Yakobson and his group:

  • Carbyne’s tensile strength – the ability to withstand stretching – surpasses “that of any other known material” and is double that of graphene. (Scientists had already calculated it would take an elephant on a pencil to break through a sheet of graphene.)
  • It has twice the tensile stiffness of graphene and carbon nanotubes and nearly three times that of diamond.
  • Stretching carbyne as little as 10 percent alters its electronic band gap significantly.
  • If outfitted with molecular handles at the ends, it can also be twisted to alter its band gap. With a 90-degree end-to-end rotation, it becomes a magnetic semiconductor.
  • Carbyne chains can take on side molecules that may make the chains suitable for energy storage.
  • The material is stable at room temperature, largely resisting crosslinks with nearby chains.

Nanotubes aren't stiff if they aren't straight

Posted by Stephanie C on October 3rd, 2013

"This montage includes images of carbon nanotube forests. New research explains why the CNT forests have less stiffness than expected. (Credit: Images courtesy of Justin Chow)"

Materials scientists have pursued the question of why vertically aligned carbon nanotube forests show much lower modulus values than expected. Now researchers from Georgia Tech have found that the nanotubes they fabricate contain kinks that dramatically diminish modulus value. In other words, the nanotubes are not straight; therefore, they are not stiff.

The government-funded research was recently published in Carbon, and the first sentence of the Abstract reads, “Waviness is invariably present in vertically-aligned Carbon Nanotubes (CNTs) regardless of how controlled the fabrication process is.”  As described in the journal article, and in a reprinted news article at, the inescapably wavy nanotube forests afford possible heat management applications:

Carbon nanotubes provide many attractive properties, including high electrical and thermal conductivity, and high strength. Individual carbon nanotubes have a modulus ranging from 100 gigapascals to 1.5 terapascals. Arrays of vertically-aligned carbon nanotubes with a low density would be expected to a have an effective modulus of at least five to 150 gigapascals, Sitaraman said, but scientists have typically measured values that are four orders or magnitude less — between one and 10 megapascals.

To look for potential explanations, the researchers examined the carbon nanotubes using scanning electron microscopes located in Georgia Tech’s Institute for Electronics and Nanotechnology facilities. At magnification of 10,000 times, they saw the waviness in sections of the nanotubes.

“We found very tiny kinks in the carbon nanotubes,” said Sitaraman. “Although they appeared to be perfectly straight, there was waviness in them. The more waviness we saw, the lower their stiffness was.”

Foresight Invitational Workshop: Nanotechnology for Developing Countries

Posted by Jim Lewis on September 30th, 2013

Nanotechnology for Developing Countries: the 2014 Foresight Invitational Workshop
February 7-9, 2014
Crowne Plaza Cabana Hotel, Palo Alto
Silicon Valley, California, USA


Nanoscale technologies have the potential to bring immense benefits to developing countries, in areas ranging from water and energy to health and environmental restoration. But the challenges are correspondingly large; required steps include:

• Identify nanotechnologies that can make a difference near-term
• Design and build products that will actually be useful
• Bring these to market at affordable price points
• Balance intellectual property interests
• Speed enterprises past the “Valley of Death”
• Solve support and maintenance issues
• Avoid solving problems that local economies are already handling well

It’s time to gather the major players to tackle these in an invitational workshop, held in the center of high-tech entrepreneurship: Silicon Valley. Researchers, product developers, IP specialists, funders, and those with experience tackling real-world problems in developing countries will come together to find ways to “fast track” nanotechnologies to make a positive difference.

Once candidate research advances, technologies, or products are identified, vigorous efforts will be made to connect innovators with funders having experience in nano-based products. Additionally, it is understood that developing country markets have special requirements and new companies will need targeted advice to succeed.

This meeting is being held in parallel with Foresight’s “Integration Conference” to enable us to take advantage of the technical expertise gathered there.

The goal is to keep this initial workshop relatively small to enable intense interaction. Those requesting an invitation should send an email to by October 16 with name and contact info.

We look forward to hearing from you soon!

Computational design of protein-small molecule interactions

Posted by Jim Lewis on September 26th, 2013

Digoxigenin, from the Wikimedia Commons

The modular molecular composite nanosystems (MMCNs) approach to developing atomically precise manufacturing, as described in the Technology Roadmap for Productive Nanosystems envisions million-atom-scale DNA frameworks with dense arrays of atomically precise binding sites for various functional components, with specially engineered proteins binding specific functional components to specific sites on the DNA frameworks. We have frequently highlighted here improvements in DNA nanotechnology to precisely position individual components, but until now a general purpose method to engineer proteins to bind specific small molecules has been elusive. A hat tip to for reprinting this University of Washington press release describing recent work from the laboratory of David Baker, who shared the 2004 Foresight Feynman Prize for Theoretical Nanotechnology. From “Pico-world dragnets: Computer-designed proteins recognize and bind small molecules“:

Computer-designed proteins that can recognize and interact with small biological molecules are now a reality. Scientists have succeeded in creating a protein molecule that can be programmed to unite with three different steroids.

The achievement could have far wider ranging applications in medicine and other fields, according to the Protein Design Institute at the University of Washington.

“This is major step toward building proteins for use as biosensors or molecular sponges, or in synthetic biology — giving organisms new tools to perform a task,” said one of the lead researchers, Christine E. Tinberg, a postdoctoral fellow in biochemistry at the UW.

The approach they took appears in the Sept. 4 online issue of Nature. Tinberg and Sagar D. Khare headed the study under the direction of David Baker, UW professor of biochemistry and Howard Hughes Medical Institute investigator. Khare is currently an assistant professor at Rutgers University.

Building a hub for nanotech advancement

Posted by Stephanie C on September 17th, 2013

"An artist's rendering of what a possible computer chip manufacturing site might look like in Marcy." credit:

Nanotechnology draws from physics, chemistry, engineering, computation, etc., and this multi-disciplinary nature has served as a major speed bump in achievement of envisioned nanotech goals. There has been substantial concern that the U.S. is lagging behind other countries in nanotech R&D. Now researchers, companies, and politicians are coming together to create a much-needed physical hub for promoting and funding multi-disciplinary progress toward advanced technologies. The location: New York. The focus: chips.

Recently described at in an article entitled New York State: Building a Nano Empire :

For at least a decade, major nanotechnology players have been attracted by the intellectual center SUNY’s College of Nanoscale Science and Engineering has created in Albany. And now, Gov. Andrew Cuomo’s 2011 announcement of a $4.8 billion partnership with private companies — including Intel, Samsung, TSMC, IBM and Global Foundries — to develop the next generation of computer chip manufacturing is gaining traction.

“The biggest companies are behind it,” Singer said. “They really believe it will give them the competitive edge that will make it unbeatable, and they have the wherewithal to make it happen.”

And biotech is getting in on the action. Earlier this summer, SUNY CNSE announced a biotech partnership aimed at “nanotech-enabled cancer research”:

Albany, NY and Pittsfield, MA – Underscoring the strategic blueprint of Governor Andrew M. Cuomo in fueling New York’s growing reputation as a hub for nanotechnology-enabled innovation, SUNY’s College of Nanoscale Science and Engineering (CNSE) and Pittsfield, Massachusetts-based Nuclea Biotechnologies, Inc. (Nuclea) today announced the launch of a $1 million research partnership to enable the development and commercialization of a high-throughput nanochip to accelerate the diagnosis and treatment of breast, colon, prostate and other cancers.

“Driven by the vision and leadership of Governor Andrew Cuomo, New York is recognized as the leading global hub for nanotechnology education and innovation, including an expanding footprint in critical 21st century fields such as life sciences,” said Dr. Alain E. Kaloyeros, CNSE Senior Vice President and CEO. “This public-private partnership with Nuclea Biotechnologies expands CNSE’s cutting-edge research in the nanobioscience arena, and further illustrates its role in accelerating advanced technologies and attracting high-tech companies to New York.”

“This research agreement is a perfect marriage of biotechnology and nanotechnology,” said Patrick Muraca, President and CEO of Nuclea. “CNSE’s global reputation as the world leader in nanoscale engineering will lend critical expertise in developing the miniature version of our protein chip, which is an important element for us as we work toward commercialization. We’ve assembled a great team and look forward to this collaboration with CNSE.”

Chips, which are for the most part continuing on cycles of iterative miniaturization and are still on the millimeter (bulk) scale despite the use of the term ‘nanotechnology’, remain indisputably relevant to near-term advanced technologies. Do these NY-based efforts help restore the standing of the US in global nanotech R&D?

The “molecular threading” technique disclosed by Aeon Biowares that was the topic of our previous post was presented as a great improvement over earlier bulk methods for stretching DNA, such as “molecular combing”, and the researchers speculated that it might also be useful for fabricating arrays of nanowires. As a starting point to thinking about what molecular threading might make possible, it might be useful to consider what current methods like molecular combing can accomplish. A hat tip to Josh Hall for pointing to this example of what can already be done in terms of using DNA strands to assemble functional arrays “Stanford scientists use DNA to assemble a transistor from graphene“.

DNA is the blueprint for life. Could it also become the template for making a new generation of computer chips based not on silicon, but on an experimental material known as graphene?

That’s the theory behind a process that Stanford chemical engineering professor Zhenan Bao reveals in Nature Communications [abstract]. …

Graphene has the physical and electrical properties to become a next-generation semiconductor material – if researchers can figure out how to mass-produce it.

Those Nanodot readers who heard very interesting research results from Halcyon Molecular discussed at the Foresight Institute 25th Anniversary Reunion Conference (see here and here and these videos) will be interested in this update on the “Molecular Threading” portion of that technology found on

Teams of researchers from Harvard University and Halcyon Molecular, Inc. have disclosed “Molecular Threading,” the first technology to allow single DNA molecules to be drawn from solution and precisely manipulated, allowing for faster, cheaper, more accurate DNA sequencing.

This novel technology pulls single high-molecular weight DNA molecules from solution into air and then places them onto any surface. Halcyon Molecular developed the processes and the intellectual property is now owned by Palo Alto-based biotechnology firm Aeon Biowares.
