Abstract
Biological synthesis of metal nanoparticles has caught the interest of scientists due to the environment friendly synthesis approach which yields metallic nanoparticles with antimicrobial potency. In the present study silver nanoparticles were produced using a green method with the assistance of Fusarium sp. fungal cell filtrate and their antimicrobial potency was explored. The silver nanoparticles depicted a surface plasma resonance of 434 nm when run in the Ultra Violet–Visible Spectrophotometer. The functional group present in the nanoparticles were investigated using an Attenuated Total Reflectance-Fourier Transform Infrared where –OH, C–H, amide I and amide II functional groups were notable. The morphology and crystallinity of the produced silver nanoparticles was investigated with the help of a Scanning Electron Microscope and X-ray Diffraction. The X-ray diffraction results revealed that the nanoparticles were crystalline in nature with a face centred cubic structure and a crystallite size of 38.5 nm. The Scanning Electron Microscope revealed that the nanoparticles were spherical with sizes ranging between 3 to 43 nm. Antimicrobial studies of the synthesised silver nanoparticles were conducted at different concentrations (1 mM, 10 mM, 20 mM and 100 mM) against disease causing microorganisms Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, the results showed that at a concentration of 1 mM there was no inhibition but as the concentration was increased to 20 mM and 100 mM, there was a notable inhibition with the maximum inhibition zone being 17 ± 0.6 mm.
