ABSTRACT:
The synthesis of nanoparticles using plants is a newly evolving research interest in the field of nanotechnology. Medically important plants have high photochemical which is involved in the reduction of silver ions to silver nanoparticles. In this present investigation we explore the environmental benign synthesis of antimicrobial silver nanoparticles using Annona squamosa leaves extract. The fabricated silver nanoparticles were confirmed by colour change from pale yellow to brown colour. UV-vis spectrophotometer shows the surface Plasmon resonance at 460 nm for synthesized silver nanoparticles in the reaction mixture. Scanning Electron Microscope analysis showed that the silver nanoparticles renged in the size from 40-50 nm with spherical shapes. Energy dispersive X-ray spectroscopy elucidates the chemical nature of the synthesized silver nanoparticles which showed a strong peak at the energy of 3 keV for silver. Further, the antimicrobial activities of silver nanoparticles were carried out against pathogenic bacteria and fungi by using agar well diffusion method. The antimicrobial property show high toxicity and inhibition against microbes.
