NIR Light, Gold Nanoparticles Combine to Inactivate Bacteria
HOUSTON, April 4, 2016 — A rapid photothermal technique has near-infrared (NIR) light to inactivate bacterial cells such as E. coli deposted on surfaces coated with gold nanoparticles. The method could one day help hospitals treat some common infections without using antibiotics, which could help reduce antibiotic resistance. Scientists from the University of Houston created nanoporous gold disks (NPGDs) in the lab by dissolving gold and reducing it to nanometer-scale particles. Once miniaturized, the particles
