Abstract:

In this study, the mixture of Ag+/Ni2+ was reduced to Ag/Ni BMNPs using Tamarindus indica Aqueous Stem Extract as a green reducing agent. The formation of Ag/Ni bimetallic nanoparticles was first observed based on the visual change in color of the reaction mixture at room temperature from light brown to deep brown within 20 min. UV analysis of the sample revealed that the maximum absorption peak was at absorbance of 0.8 with corresponding wavelength (λ max) at 500 nm. The FT-IR studies detected the presence of C-H, C-O, N-H, O-H and C=C functional groups as revealed by different absorption bands. Similarly, the surface morphology of the nanoparticles as revealed by SEM result is spherical. Furthermore, the synthesized Ag/Ni BMNPs were examined for antimicrobial efficacy against S. aureus, P. aeruginosa, C. albicans, and A. niger with augmentin being used as control throughout the studies. Although the inhibition zone increases with increase in concentrations of Ag/Ni BMNP of all the pathogens, P. aeruginosa, demonstrated higher zone of inhibition as compared to other pathogens, hence, Ag/Ni BMNPs may be a potential antimicrobial agent for the posterity.
