Abstract
Titanium dioxide (TiO2) is one of the most widely used nanomaterials due to its potential advantages such as anti-microbial effects and toxic gas degradation. These properties arise from photocatalytic activity of TiO2 when exposed to UV light. However, there are limitations for applications in the condition without UV. At present, ion-doped TiO2 is commonly activated by visible light from either sun light or fluorescent lamps. The use of ion-doped TiO2 has tendency to increase in the near future. Even though there are several reports on their synthesis, the antibacterial effects of ion-doped TiO2 are still lacking. In this study, antibacterial effects against gram positive and gram negative bacteria under fluorescent light illumination of TiO2 doped with different types of non-metal and metal ions were investigated. The results from this work would be essential as a selection guidance of ion-doped TiO2 with maximum efficiency for specific products in industrial level. ฉ2010 IEEE.
