Characterizing Gold Nanoparticles

Warren Chan, Ph.D., and his colleagues at the University of Toronto, investigated how the size and shape of gold nanoparticles influenced how well cells were able to take up the nanoparticles. The investigators began by preparing nanoparticles ranging from 14 nanometers to 74 nanometers in diameter and ranging in shape from round to oval to rod-shaped and then observed how well each type of particle was taken up by cells growing in culture.
