In the present investigation, aqueous leaf extracts of a medicinal plant, Ficus copiosa was utilized to construct AgNPs. The synthesized AgNPs was characterized by Ultraviolet-visible (UV-vis), Fourier Transform-infrared (FT-IR), X-ray Diffraction (XRD) spectrometer and Scanning Electron Microscopy (SEM) analysis. The phytosynthesized AgNPs exhibited comparable antimicrobial activity with two reference antibiotics against five indicator micro-organisms including two gram-positive (G+) bacteria, two gram-negative (G-) bacteria and a Protozoa (Pz). Study of the minimum inhibition concentration shows the two gram-negative bacteria to be more susceptible to AgNPs than the two gram-positive bacteria. The organisms included in the study are namely, B. Subtilis (G+), S. aureus (G+), E. coli (G-), S. pneumonia (G-) and T. vaginalis (Pz). Agar Disc diffusion technique was employed to assess the efficacy of the silver nanoparticles on the micro-organisms.</p>}, number={3}, journal={British Journal of Healthcare and Medical Research}, author={Timi, David and Gopalakrishnan, Subramaniyam and Maino, Macquin}, year={2019}, month={Dec.}, pages={06–15} }
