IEEE Spectrum: American Chemical Society Touts Nanobots as Nanotechnology’s Big Impact

Folks at the Foresight Institute can take heart that at least the American Chemical Society (ACS) is promoting the idea that nanobots and nanoassemblers are how nanotechnology will have its big impact.

New force-fluorescence device measures motion previously undetectable

A hybrid device combining force and fluorescence developed by researchers at the University of Illinois has made possible the accurate detection of nanometer-scale motion of biomolecules caused by pico-newton forces.

Tumors gobble up nanoparticles

A nanoparticle drug delivery system designed for brain tumor therapy has shown promising tumor cell selectivity in a novel cell culture model devised by University of Nottingham scientists. 

The nanoparticles used in this study were prepared from a novel biodegradable polymer poly(glycerol adipate). The polymer has been further modified to enhance incorporation of drugs and make the nanoparticles more effective.

Silicon nanoparticles enhance performance of solar cells

Placing a film of silicon nanoparticles onto a silicon solar cell can boost power, reduce heat and prolong the cell’s life, researchers now report.

“Integrating a high-quality film of silicon nanoparticles 1 nanometer in size directly onto silicon solar cells improves power performance by 60 percent in the ultraviolet range of the spectrum,” said Munir Nayfeh, a physicist at the University of Illinois and corresponding author of a paper accepted for publication in Applied Physics Letters.

Beyond batteries: Storing power in a sheet of paper

Researchers at Rensselaer Polytechnic Institute have developed a new energy storage device that easily could be mistaken for a simple sheet of black paper.

The nanoengineered battery is lightweight, ultra thin, completely flexible, and geared toward meeting the trickiest design and energy requirements of tomorrow’s gadgets, implantable medical equipment, and transportation vehicles.

Anthrax vaccine produces immunity with nanoparticles, not needles

A vaccine against anthrax that is more effective and easier to administer than the present vaccine has proved highly effective in tests in mice and guinea pigs, report University of Michigan Medical School scientists in the August issue of Infection and Immunity.

The scientists were able to trigger a strong immune response by treating the inside of the animals’ noses with a “nanoemulsion” – a suspension of water, soybean oil, alcohol and surfactant emulsified to create droplets of only 200 to 300 nanometers in size. It would take about 265 of the droplets lined up side by side to equal the width of a human hair.

Computing breakthrough could elevate security to unprecedented levels

By using pulses of light to dramatically accelerate quantum computers, University of Michigan researchers have made strides in technology that could foil national and personal security threats.

It’s a leap, they say, that could lead to tougher protections of information and quicker deciphering of hackers’ encryption codes.
