Antibacterial by use SnO2 Nanoparticle by Hydrothermal Method

This study investigated the effect of different concentration on the preparation of SnO2 nanoparticles by hydrothermal method. The results showed that a significant impact on the surface morphology and antibacterial activity of the SnO2nanoparticles. Fesem scanning of the prepared SnO2 particles, showed that, it has a semi-spherical circumferential shape, and the particles are agglomerated, irregular in shape, with an average particle size of (35 nm), and its crystal size ranges within (24.85-25.12 nm). The findings of the inhibition zone diameters for SnO2 nanoparticles on isolates of Gram-positive S.aureus and Gram-negative E.Coli. Their findings showed that the most effective inhibitor of both Gram-negative and Gram-positive bacteria is SnO2 nanoparticles produced.
