Silver nanoparticles (Ag NPs) are prepared by green, biological, physical and chemical approaches. Their biosynthesis involves the use of fungi, yeast, bacteria, plants and algal extracts. Physical methods include evaporation, arc-discharge, condensation, direct current (DC), magnetron sputtering and energy ball milling method. Chemical methods involve the reduction of silver salt. FTIR, UV-Vis spectroscopy, X-ray diffractometry and X-ray photoelectron spectroscopy are used for their characterization. Ag NPs find various technological applications and also possess anticancer, antimicrobial, anti-angiogenesis, anti-inflammatory, antiplatelet, anti-proteolytic and antifungal activities and also used in lung cancer chemoprevention, food packing, soaps, toothpastes, shampoos, detergents and cosmetics.
