Nano fiber feels forces and hears sounds made by cells

Engineers at the University of California San Diego have developed a miniature device that's sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells.

Towards stable propagation of light in nano-photonic fibers

Devices based on light, rather than electrons, could revolutionize the speed and security of our future computers. However, one of the major challenges in today's physics is the design of photonic devices, able to transport ...

Tetrapod nanocrystals light the way to stronger polymers

Fluorescent tetrapod nanocrystals could light the way to the future design of stronger polymer nanocomposites. A team of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley ...

A breakthrough in plasmonics

EPFL scientists have discovered how optical signal transmission can be controlled, paving the way for the integration of plasmonics with conventional electronic circuits.

Nanocrystal-coated fibers might reduce wasted energy

( -- Researchers are developing a technique that uses nanotechnology to harvest energy from hot pipes or engine components to potentially recover energy wasted in factories, power plants and cars.
