FACILE SYNTHESIS OF ZN-AG DOPED FUNCTIONAL NANOPARTICLES BY CO-PRECIPITATION TECHNIQUE USING TAMARINDAS INDICA LEAVES & THEIR ANTIMICROBIAL APPLICATIONS

The synthesis of metal oxide nanoparticles has emerged as a burgeoning field of research due to its promising applications in advancing technological frontiers. Particularly, the utilization of biologically derived nanomaterials has gained significant traction within the realm of nanotechnology. Tamarindus indica plant extract has demonstrated efficacy as a viable precursor for the synthesis of silver nanoparticles. Tamarindus indica, being a locally abundant plant, boasts a rich composition of essential amino acids and vitamins. This investigation presents the biosynthesis of metal oxide nanoparticles using an aqueous extract derived from Tamarindus indica. The aqueous extract and resultant nanoparticles underwent comprehensive characterization techniques such as XRD, DLS, UV, SEM, and EDS. Additionally, this study delves into the antimicrobial properties of the synthesized compound. By minimum inhibitory concentration (MIC) and Agar diffusion method of the extract against various test organisms was conducted, with results indicating antimicrobial activity against both gram-positive and gram-negative bacteria as well as fungi. The efficacy of the antimicrobial effect was assessed by measuring the diameter of the inhibition zone. The Zinc doped silver nanoparticles showed spherical shaped nanocrystals ranging from 200µm in SEM and exhibited potent inhibitor effect against Salmonella typhi and A. nigrospora.
