SILVER NANOPARTICLES - GREEN SYNTHESIS THROUGH MEDICINAL PLANTS EXTRACT AND ITS ANTIMICROBIAL PROSPECTS

The improved characteristics of Nanoparticles such as their size, distribution and morphology have made them to be used widely in a number of scientific fields as compared to bulk materials. Among metallic nanoparticles, silver nanoparticles are purposefully looked over for their superior properties (physical, chemical, and biological). The demand for green synthesis of nanoparticles have increased gradually due to the drawbacks of chemical synthesis. The development of sustainable and dependable methods for synthesis of Silver nanoparticles is the most essential step in the field of nanotechnology. Due to its distinctive properties and implementations in various fields like medicine, catalysis, water treatment, pollution and textile field, the researchers have shown more interest and heed towards it. In this context, biological approaches that used biological molecules derived from plant sources in the form of extracts displayed superiority over chemical and physical methods. Silver nanoparticles were synthesized using these extracts separately and their attributes were studied using Scanning electron microscopy, Transmission electron microscopy, and Fourier transform infra-red spectroscopy analysis. To maintain the appropriate size of nanoparticles, these plant-based biological molecules went highly controlled assemblage. The applications of huge variety of medicinal plants in the bio-inspired synthesis of Silver nanoparticles as well as their prospective applications as novel antimicrobial agents, various methods of characterization are mainly focused on in this investigation.
