| Research Abstract |
The photosensitization controlled by saccharide recognition on the metal nanoparticles was investigated. The boronic acid appended photosensitizers were introduced into the sugar-protected metal nanoparticles in the basic medium. In fluorescence spectra of the metal nanoparticles complex with the photosensitizers, the new emission bands were observed. When sacchrides such as glucose were added to the complex, the fluorescence spectra were changed remarkably. This means that the photosensitizers are dissociated from the surface of the metal nanoparticles with the interaction of sacchrides. Therefore, the optical properties of the metal nanoparticles-photosensitizers complexes are capable of control by molecular recognition on surface of particles.
