| Outline of Final Research Achievements |
Photodynamic therapy (PDT) using a photosensitizer capable of inducing cytotoxicity by light irradiation is effective only for the lesion closed to the body surface, due to low permeability of the near infrared light, and is ineffective for therapy targeting the deep tissues. To solve the problem, we studied using Cherenkov light generated by β+-ray emission of a PET nuclide as a internal light source. We have given the PDT effect by Cherenkov light to the innovative "Theranostics (a treatment and diagnostic enforcement) technology" consisting of the specific antibody/Zr-89 labeled-drug delivery system (DDS) that we have ever established. We were newly able to verify some of the new basic technologies to overcome the problem (limit) of the PDT effect.
