What is Radiation in the Context of Nanotechnology?
Radiation refers to the emission of energy as electromagnetic waves or as moving subatomic particles. In the context of
Nanotechnology, radiation plays a crucial role both as a tool for manipulating materials at the nanoscale and as a phenomenon that nanomaterials must often be engineered to withstand or utilize.
