Latest Invention: LED Light Bulbs that Makes Use of Salmon DNA

Share

Researchers from the University of Connecticut recently unveiled their latest invention, which is a long-lasting LED light bulb that makes use of salmon DNA.

Scientists added two different fluorescent colors to the DNA molecules, the dyes being spaced from each other at a distance ranging from 2 to 10 nanometers. After the colors were added, the DNA molecules are spun into nanofibers. The UV light that produces LED is then covered with DNA nanofibers.

David Walt, a chemistry professor at Tufts University, explained: "When UV light is shined on the material, one dye absorbs the energy and produces blue light. If the other dye molecule is at the right distance, it will absorb part of that blue-light energy and emit orange light." By changing the ratios of dyes, one can adjust the quality of light, for example turning cool white into warm white.

But just like all latest inventions, this one still requires more studying. Besides there is currently no information regarding how many lumens per watt the salmon DNA LEDs generate, which is why it is too early to say anything about longer life or improved light quality. More information is available here .
