Despite performing many methods towards the bacterial pollution, containing many detection and sterilization techniques, there is still a lack of effective means. Herein, a novel copper\n modified titanium (Cu@TiO<jats:sub>2<\/jats:sub>) nanocomposites were resoundingly synthesized via the well-known sol-gel process, which revealed a significant antibacterial activity under the illumination of sunlight. The XRD, Raman spectroscopy and TEM images showed that the Cu@TiO<jats:sub>2<\/jats:sub> nanocomposites\n with a globular shape are anatase phase, Moreover, low temperature physical adsorption test and UV- visible spectrum indicate Cu<jats:sub>0.01<\/jats:sub> @TiO<jats:sub>2<\/jats:sub> owns a supernal specific area (80 m<jats:sup>2<\/jats:sup>\/g) and the high visible light absorbing ability. Furthermore, the novel Cu@TiO<jats:sub>2<\/jats:sub>\n nanocomposites showed an unprecedented photocatalytic capacity towards <jats:italic>Escherichia Coli (E. coli)<\/jats:italic> bacteria. <jats:italic>In vitro,<\/jats:italic> Cu@TiO<jats:sub>2<\/jats:sub> nanocomposites can kill almost 98.7% <jats:italic>E. coli<\/jats:italic> under 60 min simulated solar light irradiation than that of TiO <jats:sub>2<\/jats:sub>(31.3 %). This\n study suggests that the Cu@TiO<jats:sub>2<\/jats:sub> will be as a potential material for ameliorating antibiotic-resistant bacteria in food
