N2 - In this study, we assessed antifungal effects of the nano-metals loaded titanium dioxide (TiO2) on Aspergillus niger spore. The nano-metals (Ag, Cu and Ni) were loaded to TiO2 by incipient wetness impregnation. The antifungal experiments were conducted under four situations: in the darkness (Dark), illuminated with ultraviolet lamp (UV), exposure to 5 ppm of ozone (O3), exposure to 5-ppm ozone and illuminated with ultraviolet lamp simultaneously (O3+UV). In the case of Dark, the antifungal effect of the nano-Ag loaded TiO2 is better than that of nano-Cu and Ni. In the case of UV, the quartz chips coated with TiO2 and nano-metals loaded TiO2 showed worse antifungal effect than the bare chip. In the case of O3, the deactivation of Aspergillus niger spore on the bare quartz chips was faster than that on the catalyst coated chips. Overall, the antifungal effects of these four situations on the Aspergillus niger spore is in the order of: UV+O3>UV>O 3>Dark.
