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
