GREEN SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLE USING Phyllanthus emblica AND Cinnamomum verum EXTRACT

Introduction: Phyllanthus emblica is a short to medium sized tree with greenish yellow fruits. Phyllanthus emblica is a good source for vitamin c. It possesses a good amount of antioxidant property and has been proved to be effective in the treatment of toothache, gingival inflammation and other types of ulcer. Silver nanoparticles (AgNPs) have emerged as one of the promising nanoparticles due to their unique properties such as surface enhanced scattering, thermal conductivity. Nanotechnology is a term that involves a spectrum of technologies, techniques and processes that deal with a matter at nanoscale falling between 1nanometer to 100 nm in size. The study aims at synthesizing silver nanoparticles using Phyllanthus emblica and Cinnamomum verum and to characterize its properties by transmission electron microscope method.

Materials and Methods: Phyllanthus emblica fruit extract and Cinnamomum verum powder was purchased from the herbal care center. 0.5 grams of both the extract was measured and added to a conical flask containing 50 ml of distilled water. Then the extract was heated at 60°C for 7-8 minutes with the help of a heating mantle, 10 ml of the plant extract is added with 90 ml distilled water on to which 0.0169 grams of silver nitrate was also added and placed in the shaker for uniform distribution and the color change is noted periodically with an interval of one hour for 2 days. TEM analysis method was used to characterize the nanoparticle.

Results: UV-visible spectroscopy of the AgNPs was performed to investigate the effect of variation of reaction parameters such as temperature, PH and concentration of reactants on the synthesis of silver nanoparticle using Amla and cinnamon fruit extract. This method yields stable, spherical silver nanoparticles in the size range 5-45 nm.

Conclusion: The present study was successful in synthesizing plant mediated silver nanoparticles using Amla and cinnamon formulation. Most of the synthesized silver nanoparticles were spherical in shape and were in the size range of 5-45 nm.
