Synthesis And Characterization of Flourine Doped Tin Dioxide (Sno2) Nanoparticles Using Prosopis Juliflora Leaf Extract and Their Biological Activities

Abstract

The field of nanotechnology is one of the most active research areas in modern materials science. Types of metals used in the manufacture of nanoparticles. SnO₂ is an important n-type wide band semiconductor that appears as one of the most important classes due to the diversity of controllable physicochemical characteristics of the nanoparticles from SnO₂. Therefore, the development of highly effective nanomaterials with advanced antibacterial functions is of the utmost importance. The aim of this study was to synthesize 10% F doped tin dioxide (SnO₂) (FTO) nanoparticles using the leaf extract of Prosopis juliflora to determine its antibiotic activity against selected microbial strains. The characterization of the synthesized nanoparticles was studied by scanning electron microscopy, transmission electron microscopy and UV–Vis–IR spectroscopy. Particle size was obtained in the range of 60 ~ 90nm. The antibiotic activity of SnO₂ nanoparticles doped with 10%F was 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 10 % F doped Tin dioxide (SnO₂) nanoparticles (F- doped SnO₂) exhibited the good antimicrobial effects were observed.
