Assessment of antimicrobial activity of nanosized Ag doped TiO2 colloids
Abstractnbsp;nbsp;In the present research, the antimicrobial effects of nanosized silver (Ag) doped TiO2 colloidal solutions prepared using a sol–gel technique were investigated. In order to determine the solution characteristics, the turbidity, viscosity and pH of the colloidal solutions were measured. Differential thermal analysis-thermogravimetry equipment was used to determine the chemical structures and reaction types of the films formed from these solutions. The morphology of Ag doped TiO2 nanoparticles was evaluated by atomic force microscopy. The disc diffusion method was employed to explore antimicrobial activity, and the Broth Microdilution method was used to obtain MIC values of nanosized Ag doped TiO2 colloidal solutions against the test microorganisms Escherichia coli,...
