PROBLEM TO BE SOLVED: To provide a method for producing an antibacterial base material, which is prepared by depositing nanoparticles to a titanium oxide base material and can exhibit high bactericidal effect, and to provide the antibacterial base material.SOLUTION: Sterilization performance is improved when a mesoporous titanium oxide base material is formed and silver nanoparticles of single nano size are deposited to it. Approximately 100% disinfection on Escherichia coli under UV irradiation is achieved when the silver nanoparticles of single size are deposited from an arc plasma evaporation source to the mesoporous titanium oxide base material formed of mesoporous titanium oxide particles supported on a glass substrate beneath.COPYRIGHT: (C)2013,JPO&INPIT【課題】ナノ粒子を酸化チタン基材に付けた高い殺菌効果を発揮できる抗菌性基材の製造方法、並びに抗菌性基材を提供する。【解決手段】 メソポーラス酸化チタン基材を形成し、それにシングルナノサイズの銀ナノ粒子を坦持して滅菌性を上げる。アークプラズマ蒸着源で銀ナノ粒子を、下方のガラス基板上につけたメソポーラスな酸化チタン粒子からなるメソポーラス酸化チタン基材にシングルサイズのナノ粒子を付けて紫外線で大腸菌に照射することで略100%死滅させることができ【選択図】 図3
