| Research Abstract |
A simple and easily controllable immobilization method for photosensitizer dyes and the resulting photosensitizer dye nanoparticle-coated membranes (PDNMs) that generate singlet oxygen (1^^O_2) under atmospheric conditions were demonstrated. A 100% photosensitizer dye nanoparticles layer that is less than 1 μ m thick on a membrane filter caused quantitative 1^^O_2 production under illumination. The thin layer promotes effective light absorption as well as significantly slowed deactivation of 1^^O_2 by supporting materials. Moreover, the PDNMs were highly resistant to photobleaching of dye itself.
