Silver nanowire sensors hold promise for prosthetics, robotics

North Carolina State University researchers have used silver nanowires to develop wearable, multifunctional sensors that could be used in biomedical, military or athletic applications, including new prosthetics, robotic systems and flexible touch panels. The sensors can measure strain, pressure, human touch and bioelectronic signals such as electrocardiograms.

New technique allows robotic 'nanobiopsies' of living cells

Researchers at UC Santa Cruz have developed a robotic "nanobiopsy" system that can extract tiny samples from inside a living cell without killing it. The single-cell nanobiopsy technique is a powerful tool for scientists working to understand the dynamic processes that occur within living cells.

A deeper look at interfaces

A technique developed at Berkeley Lab's Advanced Light Source makes it possible for the first time to selectively study the electronic structure of buried interfaces in multilayer nanodevices. The technique is called Standing Wave Angle-Resolved Photoemission Spectroscopy.

Quantum physics could make secure, single-use computer memories possible

Computer security systems may one day get a boost from quantum physics, as a result of recent research from the National Institute of Standards and Technology (NIST). Computer scientist Yi-Kai Liu has devised a way to make a security device that has proved notoriously difficult to build - a 'one-shot' memory unit, whose contents can be read only a single time.

Layered security: Carbon nanotubes promise improved flame-resistant coating

Using an approach akin to assembling a club sandwich at the nanoscale, National Institute of Standards and Technology (NIST) researchers have succeeded in crafting a uniform, multi-walled carbon-nanotube-based coating that greatly reduces the flammability of foam commonly used in upholstered furniture and other soft furnishings.

Microscopic fountain pen adds new functionality to AFM microscopy

An AFM's cantilever has a fine tip that can be used to map surfaces at the nanoscale. The movements of the tip are monitored using laser light reflected from the cantilever. If you could manufacture a hollow cantilever and pass a liquid through it, as happens in a fountain pen, then you could kill two birds with one stone.

World's tiniest drug cabinets could be attached to cancerous cells for long term treatment

As if being sick weren't bad enough, there's also the fear of frequent injections, side effects and overdosing on you medication. Now a team of researchers from University of Copenhagen, Department of Chemistry, Nano- science center and the Institut Laue-Langevin, have shown that reservoirs of anti-viral pharmaceuticals could be manufactured to bind specifically to infected tissue such as cancer cells for the slow concentrated delivery of drug treatments.
