Green Synthesis of Silver Nanoparticles

Development of reliable and eco-accommodating methods for the synthesis of nanoparticles is a vital step in the field of nanotechnology. The remarkable chemical, physical, and biological characteristics of silver nanoparticles make them significant. Nowadays, due to the growing demand for environmentally benign technology for material synthesis, biosynthesis of silver nanoparticles (Ag Nps) has attracted a lot of attention in industrialized nations. Among the various types of nanoparticles and their strategy for synthesis, because of their special physicochemical and biological characteristics, silver nanoparticles created through green synthesis have drawn considerable interest in the biomedical, cellular imaging, cosmetics, drug delivery, food, and agrochemical industries. The size distributions and resultant nanostructure studies from the transmission electron microscopy (TEM) were in perfect agreement with the characteristics of the synthesized colloidal Ag-NPs analyzed by the ultraviolet-visible (UV-vis) spectra. For the creation of silver nanoparticles (AgNPs), biomolecules from various plant parts and microbial species have been investigated. In this review, the available previously released information on AgNPs production, characterisation methods, and applications are compiled and critically analyzed.
