Nanotech discovery could lead to breakthrough in infrared satellite imaging technology

nanotechnology infrared

Rensselaer Polytechnic Institute Professor Shan-Yu Lin has developed a new nanotechnology-based “microlens” that uses gold to boost the strength of infrared imaging and could lead to a new generation of ultra-powerful satellite cameras and night-vision devices. The device, pictured, leverages the unique properties of nanoscale gold to “squeeze” light into the tiny holes in its surface. (Credit: Rensselaer Polytechnic Institute)

Spiders at the nanoscale: Molecules that behave like robots

nanotechnology molecular nanorobot

The latest installment in DNA nanotechnology has arrived: A molecular nanorobot dubbed a "spider" and labeled with green dyes traverses a substrate track built upon a DNA origami scaffold. It journeys towards its red-labeled goal by cleaving the visited substrates, thus exhibiting the characteristics of an autonomously moving, behavior-based robot at the molecular scale.

Rice researchers spin pure batches of nanotubes species

Houston, TEXAS — In two new papers, Rice University researchers report using ultracentrifugation (UCF) to create highly purified samples of…

What do we know about nano?

Tempe, ARIZONA — Nanotechnology involves manipulating the unimaginably small. A nanometer is about 5 carbon atoms in a row, or the distance your fingernail grows in one second. Matter behaves…

Researchers design new biomaterial that mimics muscle elasticity

Vancouver, CANADA — University of British Columbia (UBC) researchers have cast artificial proteins into a new solid biomaterial that very closely mimics the passive elasticity of muscle.

The approach…

Melanin-covered nanoparticles may aid cancer patients in radiation therapy by Aarti Kapoor 

Bronx, NEW YORK — Radiation therapy is often used to kill cancer cells and shrink tumors, but the amount of radiation must be limited due to its negative side-effects — one of them being the…

Survey: Hiding risks can hurt public support for nanotechnology 

Raleigh, NORTH CAROLINA — A new national survey on public attitudes toward medical applications and physical enhancements that rely on nanotechnology shows that support for the technology increases…
