Green Synthesis of Silver Nanoparticles from several NTFP Plants

Abstract

The biological synthesis of nanoparticles using plant extracts plays an important role in the field of nanotechnology. I n this study, rapid, simple approach was applied for synthesis of silver nanoparticles using Clerodendrum infortunatum , Mucuna interrupta , Phlogancanthus thyrsiflorus and Sansevieria trifasciata aqueous leaf extract. The plant extract acts both as reducing agent as well as capping agent. To identify the compounds responsible for reduction of silver ions, the functional groups present in plant extract were investigated by FTIR. Various techniques used to characterize synthesized nanoparticles are Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and UV–Visible spectrophotometer. Results confirmed that this protocol was simple, rapid, one step, eco-friendly, non-toxic and might be an alternative conventional physical/chemical methods. Conversion of silver nanoparticles takes place at room temperature without the involvement of any hazardous chemicals.
