| Outline of Final Research Achievements |
To demonstrate the concept of drug release using oxidation-reduction reactions, the model drug-carrier conjugate was prepared and evaluated the release of the model drug. The carbon nanotubes/peptides composite and fluorescein were used as a model drug carrier and a model drug, respectively, and were conjugated via disulfide bond. This conjugate released fluorescein through the disulfide cleavage induced by bioreductive compounds such as reduced glutathione. The possibility that the drug release might be controlled by oxidoreductases was also suggested.
