Valin Posted April 26, 2013 Share Posted April 26, 2013 Phys.org Ken Kingery 4/25/13 The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects. In a recently published study, scientists at the Virginia Tech Carilion Research Institute invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment. The results will allow, for the first time, the imaging of nanoscale processes, such as the engulfment of nanoparticles into cells. "We were stunned to see the large-ranged mobility in such small objects," said Deborah Kelly, an assistant professor at the Virginia Tech Carilion Research Institute. "We now have a system to watch the behaviors of therapeutic nanoparticles at atomic resolution." Nanoparticles are made of many materials and come in different shapes and sizes. In the new study, Kelly and her colleagues chose to make rod-shaped gold nanoparticles the stars of their new molecular movies. These nanoparticles, roughly the size of a virus, are used to treat various forms of cancer. Once injected, they accumulate in solid tumors. Infrared radiation is then used to heat them and destroy nearby cancerous cells. (Snip) H/T Instapundit Link to comment Share on other sites More sharing options...
nickydog Posted April 26, 2013 Share Posted April 26, 2013 It's amazing to read the kinds of things people do and are interested in. And understand! All I do is laundry, keep the house sort of clean and make dinner. 1 Link to comment Share on other sites More sharing options...

Well, it seems like it sometimes, but that is a bit of an exaggeration admittedly. Link to comment Share on other sites More sharing options...
