When green nanotechnology is used in electronics, it makes the whole device work more environmentally friendly. It works just as a virus scanner scans for viruses on your computer, but instead it's used to help the earth.
When green nanotechnology is used in things other than electronics it is used as cells. As we've learned in science, everything has cells. In sunscreen, green nanotechnology cells are used to make it more effective. In smart drugs, green nanotechnology makes the drug just as effective as traditional drugs but without the harsh side effects. In antimicrobial bandages, green nanotechnology is used with silver to take in the infected microbes to make the wound heal.
