TF and neoplasm: Similarly, transferrin (Tf) can also be introduced into SNPs via β‐CD/AD inclusion.[51] To improve PDT efficiency, Yin and colleagues developed a targeting nano‐system of heptamannosylated β‐CD and AD‐modified photosensitizer (BODIPY) (Figure 10A).[52] These nanoparticles could target tumor cells overexpressing mannose receptors to achieve targeting PDT and mitigation of toxic side effects (Figure 10B,C).
