Recently we are more conscious with covid-19 virus and other pathogens too. In order to prevent us from these micro-organisms we are using face mask, hand gloves etc which are coated with nano materials. Nano particles having antibacterial effect coated on materials will help to protect against pathogens. In the current research gold nano particles have the capability to fight against micro-organisms which is synthesized by very simple method called green synthesis. Nano particles obtained by green method is user-friendly as it is less toxic and some are non-toxic.
