Characterization and Antimicrobial Investigation of Synthesized Silver Nanoparticles (original) (raw)

Green synthesis is an ecological system for the production of eco-friendly and well characterized metallic nanoparticles using plants. In this research work, the synthesis of silver nanoparticles was from the extract of Annona muricata leaves. The characteri- zation of silver nanoparticles was done with Fourier Transform In- frared spectroscopy (FTIR), UV-vis spectrometry and transmission electron microscope to determine functional groups, shape, size and morphology of synthesized nanoparticle. The anti-antimicrobi- al potency of the synthesize nanoparticle was investigated via well diffusion method. The UV spectrum of synthesized nanoparticle re- vealed absorbance at 435.00nm which confirmed the formation of silver nanoparticle. The FTIR analysis shows bands corresponding to -OH, C=O and -NH2 nanoparticle are spherical shape of the func- tional group. The micrograph obtained from TEM analysis confirmed that the synthesized silver is spherical in shape. The antimicrobial investigation of the silver nanoparticles shows good antibacterial ac- tivity due to high zones of inhibition against test bacteria. This work revealed that the synthesized silver nanoparticles possess great an- timicrobial potency.
