Plasmonic nanostructures make graphene viable for super-fast communications

News: Photonics    September 1, 2011
On the one hand graphene, a single layer of carbon atoms in a honeycomb pattern, can move electrons (electricity) very fast and efficiently. On the other hand graphene is lousy at absorbing energy, specifically from sunlight; only about 3% is absorbed. Sounds like graphene, a wonder material in many accounts, isn’t cut out for solar [...]

A new use for nanowires: E-skin (electronic skin)

News: Nanotechnology    October 6, 2010
What’s in a word? Call it a membrane and most people associate it with something scientific. Call it skin and there are definite human associations. So when the engineers at the University of California Berkeley (USA) developed a pressure sensitive electronic material made of nanowires, is it a membrane or skin? They’d like to call [...]

Biosensors: A sensor/probe inside a single cell

News: Nanotechnology    August 16, 2010
Can scientists put sensors inside single cells? The answer used to be, yes, but not without damaging the cell (a little or a lot). Cells, human or otherwise, are very small. Human cells vary from nerve cells at about 10 microns (that’s millionths of a meter) to 50 microns for heart cells (still very small). [...]

Nanosensors testing blood for cancer markers

News: Nanomedicine    December 17, 2009
Testing lab samples of blood is one thing; there’s lots of control achieved by isolating components of the blood before testing. Testing whole blood, unfiltered and with all components in their usual mix, is another thing. The thing is; testing whole blood is what’s required in the real world. Whole blood is complicated by the [...]
