Numerous studies have reported the bactericidal activity of AgNPs, suggesting that Ag-based particles have demonstrated useful and compelling potential for antimicrobial applications. Silver nanoparticles (AgNPs) have been tried by different scientists in different fields such as organic science, drug delivery, water treatment, etc. In this review, the authors summarize the efficient synthesis methods of AgNPs, including physical, chemical, and biological methods. Among them, silver salts are useful precursors in the chemical synthesis of AgNPs.
1. Silver salts as precursors for the synthesis of AgNPs
Chemical reduction is a relatively simple, high-yield, and low-cost process through the chemical reduction of silver salts in water or organic solvents to form colloidal suspensions. Silver nitrate is the most widely used silver salt precursor. For example, spherical silver nanoparticles can be synthesized by reducing silver nitrate with glucose. Spherical silver nanoparticles can be synthesized from silver nitrate by microwave-assisted polyol process. In addition, silver nanosheets can also be synthesized by microwave-assisted reduction of silver nitrate.
2. Silver salts act as fungicides
In addition, different silver salts and their by-products are widely used as fungicides. The reported silver-based antibacterial agents include silver sulfadiazine, silver lactate, silver dimethyl hydantion and so on.
