A special issue of the International Journal of Nanomanufacturing presenting topics on manufacturing in 3D at the nanoscale (derived from the 4th International Symposium on Nanomanufacturing held at MIT in November 2006) contains a report of a nanomanipulator for the complex assembly of nanoparticles. Although the press release from Inderscience Publishers, via AAAS EurekAlert (“Are [...]

A new building block for structural DNA nanotechnology uses a 3-carbon glycerol molecule instead of the 5-carbon sugar deoxyribose found in DNA.

The nanotechnology of engineering atomic layer interfaces to produce desired properties—in this case, something called ‘improper ferroelectricity’—promises a technological revolution that may be comparable to the development of modern electronics. From a Stony Brook University news release via ScienceDaily: In the 10 April issue of Nature [abstract], a new artificial material is revealed that marks [...]

To round out our week in nanotech on an upbeat note, we have Caltech professor Michael Roukes‘ podcast over at Earth & Sky: Forever Young. In addition to the podcast, and there’s more at the Power of Small television show on medical applications of nanotechnology, which also appears to use the title Forever Young. From [...]

The peptide nanostructure is activated by a protein-cutting enzyme found on certain cancer cells so that the activated peptide aligns the crown ethers to punch holes in the cancer cell membranes.

Two companies are applying nanotechnology to develop a really cheap method to sequence individual genomes to make possible individualized medicine.

A new nanotech method of measuring “blurred” molecular motions promises to improve the accuracy of molecular motion simulations.

Foresight advisor Glenn Reynolds opines about nanotech in the NY Post for Earth Day: MIT’s Vladimir Bulovic calls nanotech a potentially “disruptive technology” in the solar-energy field, offering a complete shift from today’s fossil-fuel environment… Nanotech offers dramatic improvements on the side of energy consumption, too: As computing and other devices become smaller, they become [...]

Graphene has now been shown to retain essential properties when used to make transistors at the one-nanometer-scale.

It’s great to see ambitious goals being set in nanotechnology, like these “molecular mini-factories“. Researchers from a wide range of disciplines at Eindhoven University of Technology (TU/e) will be joining forces in the Institute for Complex Molecular Systems (ICMS). They will be investigating the exact mechanism behind self-organization, the principle behind all life on earth. [...]

In a proof-of-concept demonstration, large area graphene films several atomic layers thick were inexpensively produced.

Nanotechnology using a molecular-scale switch could enable storing half a petabyte on one square inch.

Using nanotechnology to control the spin of a single electron in a carbon nanotube might lead to replacing conventional semiconductor transistors with a carbon nanotube or single molecule.

European nanotechnology researchers have moved a gold cargo about 500 nm along a carbon nanotube ‘Monorail”.

IBM scientists provided a proof-of-concept demonstration of a new type of nanotechnology-enabled computer memory in which magnetic domain walls are moved along a nanowire “racetrack”.

Lab-on-a-chip technology has been used to automate the evolution of molecules so that this approach might prove useful for nanotech purposes.

Nanoparticles targeted to the growing blood vessels feeding tumors in rabbits shrank the tumors using far less chemotherapy drug than would have been required to shrink the tumors if the drug had been used alone.

Three short DNA strands attached to one aromatic ring containing six carbon atoms form three-legged building blocks that assemble into a dodecahedron.

A proof-of-concept application of nanotechnology to fabricate transparent organic light emitting diodes (OLEDS) small enough to serve as pixels in high-resolution displays might lead to products like flexible color monitors and “heads-up” displays in car windshields. From a Purdue University press release “Engineers make first ‘active matrix’ display using nanowires“: Engineers have created the first [...]

Current capabilities in nanotechnology not only promise better vehicles for drug delivery, but also provide materials nanoengineered to promote specific tissue healing.
