Abstract: A photosensitizer molecule increases the retention time thereof in a tumor and the enhancement of the therapy for large-volume tumors. AN-BDP is synthesized by means of introducing anthracene into BODIPY-meso, and due to the strong intermolecular ?-? interaction of anthracene, AN-BDP and an amphiphilic block copolymer DSPE-PEG2000 are self-assembled into stable nanoparticles AN-BDP NPs. By means of anthracene, AN-BDP can be excited to a triplet excited state under light irradiation and acts with O2 to generate 1O2. AN-BDP NPs are enriched at the tumor site and retained for about 10 days after tail vein injection. In a mouse tumor model having a conventional volume tumor, AN-BDP NPs can completely inhibit the growth of the tumor by means of one-time tail vein injection and one-time photoirradiation therapy.
