Description :
For green synthesis of silver nanoparticles Carica papaya leaf extract is used to potentiate extent of their antimicrobial activity against range of microorganisms. Silver nanoparticles display characteristics like size and distribution has remarkable use in numerous scientific fields. Carica papaya leaves are known for their benefits as they possess antimicrobial, anti-inflammatory, anti-proliferative, antioxidant activities, anti-dengue effects and bioremediation as well. The small size of nanoparticles is gaining importance in research for their use as potential therapeutics. Silver nanoparticles are very important especially due to their physiochemical and antimicrobial properties which are less pronounced in case of other nanoparticle. The present study assessed the characterization of silver nanoparticles using UV–Visible spectroscopy, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The synthesized nanoparticles have larger surface area compared to bulk molecule which enhances their interaction with micro-organisms and increases their antimicrobial activity. These are more soluble than bulk molecule making them easier to transport and distribute in various applications. The green synthesis of nanoparticles is simple, safe, easy, fast, economical and environment-friendly technique which adds to its advantages.
