The invention discloses a PEGylated heparin nano-micelle loaded with a photosensitizer, and the micelle is a PEGylated heparin molecule loaded with a porphyrin photosensitizer. The natural polysaccharide heparin, which is biodegradable, has good compatibility and high availability, is used as a drug carrier. By combining PEG modification and porphyrin-based photosensitizers, the targeted and long-acting drugs can be achieved. |
