Abstract

Titanium dioxide
(TiO₂) is one of the most important semiconductors. It has attracted
a growing attention in huge applications because of their unique properties. In
this present survey we are interesting to investigate the resist growth of TiO₂
thin films with various dopants against gram negative of Escherichia coli
bacteria. TiO₂ thin films were deposited on soda lime glass and tissue by
two different methods (spray pyrolysis and sol-gel) in order to study their
effect on antibacterial activity. We used two processes of bacteria and in the
both the results indicate that TiO₂ can resist the growth of E.
coli. The zone of inhibition of this bacterium is found between 11 and 17 mm.
