Abstract

Nowadays various infectious diseases are becoming more easily widespread The problem is becoming more and more complicated because of the "epidemic" of bacterial resistance, which makes broadly used antibacterial agents almost not applicable. Patients infected with multi-resistant bacteria have more severe clinical courses and require prolonged hospital treatment considering the major and critical impact of this situation must be carried out. Thus, the research of antimicrobial titanium dioxide is the most single-crystalline system of the metal oxides, and the literature on anatase TiOz is comprehensively reviewed in this study. The capability of titanium oxide had been prove from many researches all over the world. The hotocatalyst function of TiOz makes this unique material as the most famous material to be researched. Thus, in this study is done to enhance the function of TiOz by doping once again the silver solution onto the Ti02 surface. Titania-doped-silver coating were prepared on the glass microscope slide by using sol-gel dip-coating method. Various parameters were used in the research done to determine the best agents and solution to be applied in the fabrication of Ag!fi{)z sol for the antimicrobial application. The fmal products were determined as translucent coated glass slide and have a yellowish coated glass slide after heat treatment. Various material characterization tools is used to analyzed the crystalinity of the coated glass slide and sol-gel solutions in oreder to determined the present of anatase and rutile phase that play an important roles in photocatalytic activity. The enhancement of Ag behavior is found to be effectives against bacteria without any source of light. Thus, this proved that Ag!fi{)z promote more effectiveness with or without light present in the surrounding environment. This project has successfully achieved the objectives.
