Researchers have identified the activity of Silver NPs exerted the antibacterial effect in two steps. First‚ they changed the membrane potential and reduced adenosine triphosphate (ATP) synthase activities‚ thus reducing the metabolism process. Secondly‚ they declined the subunit of the ribosome for tRNA binding‚ thus collapsing its biological mechanism. At the same time‚ they proved to be less toxic to mammal cells [26]. Silver NPs with a small size and enhanced surface area produce some electronic
