Preparation and Characterization of SnO2 Nanoparticles for Antibacterial Properties

To investigate morphological, optical and antibacterial properties of SnO2 nanoparticles which are synthesized by using an easy and affordable Sol-Gel method. By using various techniques such as XRD (X-ray Powder Diffraction), FT-IR (Fourier Transform Infrared), UV-Vis, PL, SEM (Search Engine Marketing), EDAX (Energy Dispersive X-Ray Analysis), the structural, optical, composition of elements and the size of the SnO2 nanoparticles (NPs) has been discussed. The variation in properties of SnO2 as synthesized and at annealing temperatures has also been discussed. Size of tin oxide Nano particles from XRD is found in the range of 9-10 nm, and the lattice parameters about a=b=4.73060A, c=3.690A. From UV-Vis it is found that the band gap of tin oxide decreases as we increase the temperature. Active efficiency of SnO2 NPs has been tested on Gram negative (E.coli) and gram positive (Micrococcus luteus) bacteria on the growth of pure culture using zone inhibition method.
