 Silver nanoparticles, AGNPs, have been recently recognized for their use in agriculture and medicine as antibacterial, antifungal, and antioxidant agents. They arrest the growth and multiplication of many bacteria and fungi by binding with biomolecules present in microbial cells, producing reactive oxygen species and free radicals that cause apoptosis leading to cell death, and diffusing into cells to rupture their walls. Smaller nanoparticles are more toxic than bigger ones, and the toxicity of AGNPs is dependent on size, concentration, pH of medium, and exposure time to pathogens.
