Tin nano oxides (II /IV) (SnO/SnO2) were synthesized via a Sol - Gel method by using SnCl2 salt and starch media. The structures of these oxides were characterized and investigated by some spectroscopic methods such as SEM, XRD, UV, FT-IR. The effect of calcination temperature on the particle size of Tin nano oxides was investigated. The average particle size of these nano oxides are 11.75 and 11.19 nm by calculation with Debye- Scherrer equation. In the other part of this work, we study the antimicrobial properties of the synthesized synthesized metal oxides. In the results, nano-sized SnO2 is a good antimicrobial compound in the range of 10 mg per ml on the Gram negative bacteria. Nano-sized snow has not and antibacterial activity. Also the nano-sized SnO2 can to prevent of the grouting some gram negative bacteria, such as, Pseudomonas aeruginosa PTCC 1214, Escherichia coli PTCC 1330, Klebsiella and Albixs Candida PTCC 5027.
