Gold nanoparticles, which are about one-thousandth the width of a human hair, can convert light they receive from a laser into heat. This capacity, known in medicine as photothermal therapy, is effective at destroying cancer cells without harming the surrounding healthy tissue. It's one of the techniques the scientific community is exploring in depth as an alternative chemotherapy, as it is less aggressive.
