Swiss researchers have used biomolecular shuttles to capture molecular building blocks from solution and transport them across fluid flow boundaries to be further manipulated in a subsequent chamber.
Register by Sept. 5 to attend a Proposers Day webinar on either Sept. 9 or 11 to learn the technical objectives of DARPA’s new “Atoms to product: Aiming to make nanoscale benefits life-sized” program.
An interview with UK nanotechnologist Richard Jones argues that the surest and most efficient path to advanced nanomachine function will incorporate or mimic biomolecular nanomachinery rather than scaled down rigid conventional machinery.
Attaching a 200-nm-diameter magnetic bead to a 1-nm diameter synthetic molecular machine allowed optical visualization of the motion of the machine and manipulation with a magnetic tweezers.
Rice University’s breakthrough nanoporous silicon oxide technology for resistive random-access memory (RRAM) appears poised for commercialization.
Study shows more than 500 firms involved in nanobiotechnology, which is expected to soon triple in size. Research points to the importance of broad networks and deep collaborations.
With biotech fundamental to several paths to advanced nanotechnology, a way to do biotech experiments in the cloud offers small groups the chance to quickly test their ideas.
B.R.AI.N.S., Berkeley BioLabs, and Foresight Institute to build an open source biological parts repository and design and distribute a line of “How-to Build Biological Machines” educational kits.
Just when it seemed like debate over the National Nanotechnology Initiative was a thing of the past (see Foresight’s disappointment in 2008 here), disagreements regarding re-authorization and budget cuts are prompting politicians and researchers to take a detailed look at what the program supports and what it is achieving. Witnesses to the House Research Subcommittee [...]
Using an STM to precisely position indium adatoms on an indium arsenide surface, nanotechnologists have created a series of atomically precise quantum dots, and joined them with atomic precision to make quantum dot molecules, opening new avenues to construct practical quantum devices for computing and other applications.
Enveloped DNA nanostructures were developed to escape attacks from nucleases and the immune system, opening a path to ever more sophisticated DNA nanomedical devices.
The photos from the 2014 Foresight Technical Conference highlight entrepreneurial efforts in space, biotechnology, and life extension.
The complex molecular recognition code of RNA offers RNA nanotechnology a greater variety of 3D structures and functions than are present in DNA nanotechnology, but the RNA structures can be fragile. New RNA triangles that resist boiling solve this problem.
Carbon-containing functional groups decorating carbon nanotubes decompose upon heating on copper foil to form a nanotube-reinforced graphene with novel properties that mimic those of expensive indium-tin-oxide.
A swinging DNA arm added to a DNA scaffold makes it possible for two enzymes attached to the scaffold to complete a coupled chemical reaction.
A bacterium has been engineered to stably propagate a DNA written with six letters instead of the usual four, greatly expanding the number of amino acids, both natural and synthetic, that can be genetically encoded. Further work could lead to novel proteins incorporating these additional amino acids, and from there to novel materials, devices, and machines.
Two different nanotechnology-based approaches to use graphene as the basis for purification and desalination of water look promising.
A novel method to control the configuration of atoms in semiconductors grown on graphene will make possible a vast array of new optical devices, including better solar cells.
Reviewing Eric Drexler’s Radical Abundance, Phil Bowermaster provides an informed and insightful overview of the controversies that greeted the proposal for a nanotechnology aimed at developing a practical technology for atomically precise manufacturing. Along the way he shows how Drexler’s outlook evolved from 1986 to 2013.
