Anti-HER2 Affibody-Conjugated Photosensitizer for Tumor Targeting Photodynamic Therapy

Antibody-coupled photosensitive molecules can achieve an ideal tumor-specific photodynamic therapy (PDT) and show strong clinical application potential. However, some inherent disadvantages, such as long circulation half-life, poor permeation into solid tumors, and difficulty in obtaining uniform coupling products, present potential problems to clinical applications. In this study, we propose a novel design of targeting photosensitizers, based...
