(PhysOrg.com) -- The ability to manipulate light and fluids on a single chip, broadly called "optofluidics," has led to such technologies as liquid-crystal displays and liquid-filled optical fibers for fast data transfer. Optofluidics is now also on the cusp of improving such green technologies as solar-powered bioreactors, say Cornell researchers.

Electrical engineers at Duke University have developed a material that allows them to manipulate light in much the same way that electronics manipulate flowing electrons.
