Filament-shaped artificial viruses show promise in delivering genetic materials and other molecules into cultured human cells.

Chinese scientists have recently built an atomically precise structure directed by bonds between gold atoms—a crown of 36 gold atoms coordinating surrounding organic molecules.

Current nanotech capabilities have been incorporated into a proposed architecture for medical nanorobots to control epidemic diseases.

A nanotech barcode could revolutionize medical diagnostics by providing a very sensitive method of counting individual messenger RNA molecules.

Nanotech materials useful for a wide variety of applications may result from the discovery that adding very small amounts of graphene to polymers greatly increases the desirable properties of the polymers.

A nanotech approach to overcoming the resistance of some cancer cells to radiation therapy has been successfully tested in mice.

The safe commercialization of nanotech will require special attention to the manufacture and disposal of materials using carbon nanotubes.

Nanowires of indium phosphide grown directly on an electrode greatly increase the flow of electrons through a polymer film to the electrode.

Arizona State University chemists have demonstrated a nanotech version of molecular self-regulation by designing a molecule that mimics the way in which plants defend themselves from an overload of sunshine.

In an application of nanotechnology to medicine, a nanotech material has been produced that self-assembles in the presence of bodily fluids into highly hydrated fibers that stop bleeding within 15 seconds.

Nanotechnology can use catalytic motors to convert chemical to mechanical energy, using fuels that are chemically simpler than ATP and catalysts that are simpler than enzymes.

Sunday, May 18th at 7:00 PM Pacific / 10:00 PM Eastern, FastForward Radio will feature a distinguished panel discussing the Technology Roadmap for Productive Nanosystems. The panel will discuss the background and history of the roadmap, and explore how it will serve to help realize these horizons. The panelists are: Christine Peterson, Acting President of [...]

Can online gamers add to the nanotech toolkit for perfecting the de novo design of proteins that do not exist in nature?

Using a spin-on coating that is applied to a silicon wafer, nanotech researchers have developed a method for mass fabrication of nanowire photonic and electronic devices.

Researchers have joined about eight nanoparticles together to make nanostructures resembling segmented worms, and find these survive many hours.

There is hope that nanotechnology in the form of silver nanoparticles will provide protection against drug-resistant bacteria in hospitals, but there is also concern that unregulated use of silver nanoparticles in commercial products will damage the environment.

A while back Senior Associate Stuart Scott let us know that he had been selected to participate in a National Citizen’s Technology Forum process on nanotechnology, sponsored by Arizona State and University of North Carolina, among other schools. Presumably this is funded by the social science budget of the U.S. National Nanotechnology Initiative, via NSF. [...]

Some nanostructures can be improved after fabrication by a new nanotech procedure that transiently and selectively liquifies the structures to remove defects.

We’ve received an invitation to participate in the Center for Nanotechnology in Society’s project to build and critique nanotechnology scenarios. Current topics to edit in the wiki, or you can add your own: * Barless Prisons * Bionic Eyes * Living with a Brain Chip * Disease Detector * Automated Sewer Surveillance * Engineered Tissues

Studies of how molecules are released from nanoparticles when they encounter cancer cells and of how the nanoparticles break down prematurely while circulating in the blood point toward ways to improve the nanotech delivery of therapeutic drugs into cancer cells.
