+ - Researchers Use Salmon DNA to Make LED Lightbulbs->

Al writes: "Researchers from the University of Connecticut have created a new light-emitting material by doping spun strands of salmon DNA with fluorescent dyes. The material, which is robust because DNA is such a strong polymer, absorbs energy from ultraviolet light and gives off different colors depending on the amounts of dye its contains. A team led by chemistry professor Gregory Sotzing created the new material by mixing salmon DNA with two types of dye, then pumping the solution from a fine needle while a voltage is applied between the needle tip and a grounded copper plate covered with a glass slide. As the liquid jet comes out, it dries and forms long nanofibers that are deposited on the glass slide as a mat. The researchers then spin this nanofiber mat directly on the surface of an ultraviolet LED to make a white-light emitter. The color-tunable DNA material relies on an energy-transfer mechanism between two different fluorescent dyes,and the DNA keeps the dye molecules separated at a distance of 2 to 10 nanometers from each other."
