GREEN SYNTHESIS OF SILVER NANOPARTICLES USING PTERIS VITTATA L. EXTRACT AND STUDIES ON ITS ANTIBACTERIAL ACTIVITY AGAINST ESCHERICHIA COLI
AbstractThe aim of the present investigation is to synthesize and characterize silver nanoparticles (AgNP) for their antibacterial activities. Aqueous frond extract of Pteris vittata L. was used for synthesis of silver nanoparticles. The phytosynthesized silver nanoparticles were characterized using UV-Vis spectrophotometer, SEM, TEM, FE-SEM, EDS, FT-IR. Morphologically, they are spherical in shape where average size was found to be 28 nm. Phytosynthesized silver nanoparticles were further studied for their antibacterial potential. Various concentrations of silver nanoparticles were used to check antibacterial activity against E. coli (ATCC 25922) strain. Stock solution of silver nanoparticles was prepared in DMSO at 1mg/ml. Among various concentrations studied, 350 µg/ml was effective and showed optimum zone of inhibition (13 mm diameter). Hence, the present study is beneficial to focus on effective use of Pteris vittata L. for the green synthesis of AgNP’s with minimum amount of plant material as well as independent of specific pH or temperature requirements.
