moscowde writes "Researchers at Cornell University have created a so-called Nano-Lamp — a microscopic collection of light-emitting fibers with dimensions of only a few hundred nanometers. The fibers are made of a polymer spiked with ruthenium molecules in a process dubbed 'electrospinning.' The bright spots on the fibers are smaller than the wavelength of the light they emit. The nanofiber glows bright orange when exposed to an electric field and can be seen in the dark with the naked eye. A professor at Princeton University called this 'a breakthrough in the way nanosize light sources are made.' Since the nanofibers are flexible, they could potentially be used in clothing or bendable computer displays."
