Researchers have used lasers to precisely control neutrophils - a type of white blood cell - as a natural, biocompatible microrobot in living fish. The 'neutrobots' performed multiple tasks, showing they could someday deliver drugs to precise locations in the body.
Scientists have combined graphene oxide, elastin, and ethanol to develop a new method to make this material conductive so it can be heated to kill melanoma cells but not other cells around it.
