• Dark-field microscopy coupled with capillary electrophoresis to see gold nanoparticles

  Chinese scientists have combined interfacing dark field microscopy (DFM) with capillary electrophoresis (CE) and used it to “see” single gold nanoparticle (AuNPs) movement visually and in real time. The study also served to confirm the separation rules and fundamental theories of CE. more

• Gold nanoparticles reveal fingerprints

  Gold nanoparticles capped with mercaptocarboxylic acids, followed by silver precipitation, have been used to develop latent fingerprints on paper as high quality negative images. Scientists say that the effect stems from hydrogen bonding between the carboxylic group and the paper cellulose. Recoveri more

• Breakthrough in nanotechnology

  A University of Central Florida assistant professor has developed a new material using nanotechnology, which could help keep pilots and sensitive equipment safe from destructive lasers. UCF Assistant Professor Jayan Thomas, in collaboration with Carnegie Mellon University Associate Professor Rongcha more

• Photothermal Release of Singlet Oxygen from Gold Nanoparticles

  Anthracene endoperoxide ligands anchored to the surfaces of gold nanoparticles undergo bond breaking and release singlet oxygen when the nanoparticles convert 532 nm laser light to heat localized near their surfaces. more
