Whenever people talk about public health, drug-resistant superbugs are a frequent concern. How do you eliminate bacteria your best antibiotics can't kill? Google's AI came up with one solution to the superbug problem , but another one might lie in the technology that makes QLED TVs brighter and more color accurate than OLED sets .

Over the summer, a team of researchers from China published its findings on the efficacy of a new antibacterial composite — you can find the study in Acta Physico-Chimica Sinica . This material was made out of gold nanoparticles (particles of gold suspended in liquid with diameters measured in nanometers) and graphene oxide quantum dots (crystalline semiconductors, similar to the ones you find in QLED TVs). According to the study, when exposed to blue light from a 460 nanometer LED, the composite created reactive oxygen species (ROS), which are unstable molecules that contain oxygen and free radicals. ROS are particularly toxic to cells and bacteria.…
