Prosopis Juliflora Leaf Extract Mediated Synthesis Of Doped Tin Oxide Nanoparticles And Evaluation Of Antimicrobial Activity

Abstract

Nanomaterials are used in a wide range of industries, including storing energy, water treatment, nanomedicine, fuel cells, sensing, catalysis, optoelectronics, and tunable resonant devices. Varieties of metals used for the preparation of  nanoparticles. SnO₂ is a prominent n-type wide-bandgap semiconductor, and due to the variety of controllable physicochemical features of SnO₂-based nanostructures, they are emerging as one of the most significant classes. Therefore, the development of a more efficient nanomaterial with enhanced antimicrobial activity of great significance. The objective of this study was to synthesize 2% F doped Tin dioxide (SnO₂) (FTO) nanoparticles using Prosopis Juliflora leaf extract and determine its antimicrobial activity against selected microbial strains. The characterization of synthesized nanoparticles were investigated by scanning electron microscopy, transmission electron microscopy, UV–Vis–IR spectroscopy. The grain sizes in the range of 16-26 nm were obtained. The antimicrobial activities of F- doped SnO₂ nanoparticles were studied against bacteria (Escherichia coli, Staphylococcus aureus and Bacillus subtilis) and fungi (Aspergillus flavus and Aspergillus niger) using the standard disc diffusion method. The antimicrobial activity was increased directly proportional to dose-dependent manner. Experimental results demonstrated that 2% F doped Tin dioxide (SnO₂) nanoparticles (F- doped SnO₂) exhibited the good antimicrobial effects were observed.
