| Outline of Final Research Achievements |
This study aimed at the establishment of a novel cancer-targeted diagnosis-therapy workflow system by optical approach with near-infrared light suitable for clinical use. Thus, we planned to synthesize cancer-targeted photoacoustic (PA) probes which generate acoustic waves by irradiating near-infrared light, and apply these probes to in vivo PA imaging and cancer therapy utilizing heat generated in the PA wave-generating process. As a result, we succeeded in developing novel in vivo PA imaging probes based on small molecules, polymers, antibodies, and metal nanoparticles with intense PA signals. Furthermore, these probes produced heat enough for cytotoxic effect by irradiation of near-infrared light.
