DNA and quantum dots: All that glitters is not gold

Friday, January 25, 2013 - 09:31 in Physics & Chemistry

(Phys.org)—A team of researchers at the National Institute of Standards and Technology (NIST) has shown that by bringing gold nanoparticles close to the dots and using a DNA template to control the distances, the intensity of a quantum dot's fluorescence can be predictably increased or decreased. This breakthrough opens a potential path to using quantum dots as a component in better photodetectors, chemical sensors and nanoscale lasers.
