A lysosome-targeted and polarity-responsive photosensitizer for tumor specific imaging and photodynamic therapy.
A lysosome-targeted photosensitizer HBT-CUR with D-π-A feature based on 2-(2'-hydroxyphenyl) benzothiazole (HBT) and difluoroborate moieties for tumor image-guided PDT is designed and synthesized, offering a new strategy for the rational design and development of tumor PDT systems.
