Research Abstract

Water-soluble diblock copolymer, poly(N-isopropylacrylamide)-block-poly(N-vinyl-2-pyrroridone) (PNIPAMm-b-PNVPn), was found to associate with fullerene (C_60), and thus C_60 can be solubilized in water. The C_60/PNIPAMm-b-PNVPn micelle formed an aggregate comprising a C_60/PNVP hydrophobic core and a thermoresponsive PNIPAM shell. The hydrodynamic radius of the C_60-bound polymer micelle increased with increasing temperature, which was ascribed to the hydrophobic association between dehydrated PNIPAM shells above lower critical solution temperature. The generation of singlet oxygen by photosensitization by the C_60-bound polymer micelle was confirmed from photooxidation of 9,10-anthracenedipropionic acid. Furthermore, DNA was found to be cleaved by visible light irradiation in the presence of the C_60-bound polymer micelle. Therefore, there may be a hope for a pharmaceutical application of the C_60-bound polymer micelle to cancer photodynamic therapy (PDT).
