Optical devices get fishy Scientists in the US have used the DNA from fish waste to make optical components. The team, led by James Grote of the US Air Force Research Laboratory, says that the material could be used to make optical waveguides, modulators and light-emitting diodes (Appl. Phys. Lett. 87 211115). They also claim that fish DNA, which is abundant and environmentally friendly, could outperform other polymer-based devices.
DNA has unique electronic and optical properties.
