ABSTRACT
The elements present on the earth surface are hard, nonporous in daily life are now receiving greater attention for their potential function in mitigating the transmission of various nosocomial maladies. In our article work, we have revealed the photo killing consequence when 1% silver-doped Titanium dioxide TiO2 employed. However, synthesis of the nanoparticles by liquid impregnation approach later were studied using different instruments such as X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), Energy Dispersive Spectroscopy (EDS), and Scanning Electron Microscopy (SEM). Nonetheless, synergistic actions of Ag-TiO2 nanoparticle coatings when applied on glass along with venetian blind surfaces were found to be effectual in producing loss of viability of two bacteria Pseudomonas aeruginosa which is a gram negative bacteria and gram positive bacteria was Bacillus subtilis on illumination under normal light around the visible spectrum range. The bacteria lost its viability through photocatalytic mechanism. Thus, our article has provided broad insights on synergistic action of nanoparticles when applied on surfaces could be helpful in mitigating the bacteria and hence employment of such nanoparticles in preparation of medical, pharmaceutical and other facilities could act as potential in exhibiting as bactericidal agent.
