Is it necessary to remove nanoparticle ex. in water drinking or medical application.
Dose the developed GREEN synthesis methods of nanoparticles decrease the risk of their threat?
Yes It is necessary to remove NPs in drinking water because they are cytotoxic in nature. I do not think that green synthesis will reduce the toxicity. It will remain in its form
Gold is comparatively less cytotoxic to silver, so can be preferred.
Dear Foad
You can use some adsobents or use any chemical which form complex with NPs.
you may read following papers.

Dear Foad
Depends to what NPs you have in water and its toxicity. Anyway, You must reduce the NPs level to the standard level. To remove the NPs, you can apply different methods depending the NPs conc., coagulation, electrocoagulation, adsorption, NF membrane,...
