Green Tea as Biological System for the Synthesis of Silver Nanoparticles
Silver nanoparticles (Ag-NP) are being used increasingly in wound dressings, catheters and various household products due to their antimicrobial activity. Ag-NP synthesized by different methods, one of them biological method, in which extract from plant can used as reducing agent in synthesis of metal nanoparticles. Synthesis of Ag-NP in fresh green tea extract has been carried out in this work as an environment friendly approach. Ag-NP was obtained by the reduction of Ag+ ions through the action of green tea infusions. Scanning Electron Microscope (SEM) was used for the determination of the average diameter of the Ag-NP which were found of 20 nm in green tea infusion .The growth of nanoparticles is monitored by UV-VIS spectrophotometer and complemented with characterization using Transmission Electron Microscopy and Fourier Transform Infrared Spectroscopy.
