DNA and Quantum Dots: All That Glitters is Not Gold (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption The NIST team explored the behavior of quantum dots and gold nanoparticles placed in different configurations on small rectangular constructs made of self-assembled DNA (see inset for photograph). Laser light (green) allowed the team to explore changes in the fluorescent lifetime of the quantum dots when close to gold particles of different sizes.
