  Background: Silver has been widely used for disinfection because of its well known antibacterial properties. Recently, silver nanoparticles have shown higher activity killing and inhibiting bacterial reproduction. In the present work we obtained silver nanoparticles highly dispersed over nanostructured titania in order to enhance bacterial sensitivity. Materials and methods: Four different Titania-based nanoparticles were synthesized by the Sol-Gel process using Ag2SO4, AgCl, AgNO3 and CH3COOAg as silver precursor. All the materials were characterized by FTIR, UV-Vis and XPS, TEM microscopy, EDS, also BET and DRX analysis were carried out. Results: Amorphous materials were apparently obtained. Ag-TiO2 nanoparticles were tested against several Gramnegative and Gram-positive bacteria including enterophatogenic Escherichia coli and highly resistant strains such as me.. View More»
