NIST Technique Controls Sizes of Nanoparticle Clusters for EHS Studies

Caption

Transmission electron micrograph of gold nanoparticles clustering in solution. The distance between the two red arrows is approximately 280 nanometers, some 200 times smaller than the diameter of a human hair. The individual nanoparticles are approximately 15 nanometers in diameter, about the distance across 40 side-by-side sodium atoms.
