'Enlightened' atoms stage nano-riot againsts uniformity

Harnessing this behavior could lead to cooler computer chips, better bio-sensors

19-11-2008

When atoms in a crystal are struck by laser light, their electrons, excited by the light, typically begin moving back and forth together in a regular pattern, resembling nanoscale soldiers marching in a lockstep formation. But according to a new theory developed by Johns Hopkins researchers, ...

'Edible optics' could make food safer

Tufts researchers design bio-friendly optical platform for sensing applications in medicine, health, environment, communications

11-08-2008

Imagine an edible optical sensor that could be placed in produce bags to detect harmful levels of bacteria and consumed right along with the veggies. Or an implantable device that would monitor glucose in your blood for a year, then dissolve. Scientists at Tufts University's School of ...
