| Abstract(J) | 可視光型光触媒は，室内光下で抗菌・抗ウイルス等の効果を有するが，車室内で使用されるためには，即効性が必要となる．そこで可視光型光触媒の一つである，銅担持窒素ドープ酸化チタン(Cu/N-TiO2)について，大腸菌に対する短時間反応時の抗菌性能を調べるとともに，抗菌性に寄与するメカニズムを解析したので報告する． Translation |
| Abstract(E) | Visible-light photocatalysts are promising materials for car cabins, as they exhibit multiple functions under indoor light conditions, including antimicrobial and antiviral activities. Owing to the increasing demands for fast-acting sanitary materials, we studied the antimicrobial activities of nitrogen-doped titanium oxide loaded with Cu (Cu/N-TiO2), a visible-light photocatalyst, in short time reactions with Escherichia coli. The survival rate of E. coli on a Cu/N-TiO2-coated surface rapidly declined to 0% after 60 min, as assessed using a newly developed assay system and three types of resins. The morphological changes observed in E. coli resulted from the production of radicals after light exposure. |
