Abstract:Microbial contamination of drinking water poses serious health problem therefore disinfecting water by removing or killing harmful microorganism is of great importance. Common water disinfection methods include chemical disinfection, filtration, and UV disinfection. However recent research has revealed that, chemical disinfectants such as ozone, chlorine and chloramines, react with various constituents in natural water, forming disinfection by-products (DBPs). Although UV-disinfection and filtration methods are effective in eliminating microbial contamination, but their operational costs are very high and some procedures can be quite time-consuming. Recently, nanotechnology has opened an alternative method of water disinfection. Unlike the chemical disinfectants, the known antimicrobial nanomaterials are relatively inert in water and are not expected to form harmful DBPs. Nanotechnology is a field of science deals with the Nanoparticles having a size of 1-100 nm in one dimension. Nanoparticles can be broadly classified into organic nanoparticles which include carbon nanoparticles; inorganic nanoparticles include magnetic nanoparticles, metal nanoparticles which includes gold and silver nanoparticles and semi-conductor nanoparticles like titanium oxide and zinc oxide nano particles. Among these nanoparticle silver nanoparticles are the most promising one due to their strong antimicrobial activity towards many different bacteria, fungi, algae, and viruses and their relatively low toxicity to humans and also environmental friendly and very cheap. This review focuses on the green synthesis of silver nanoparticles, the mechanisms involved in its antimicrobial activity, its importance/application in commercial as well as biomedical fields discussed in detail.
