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...
