ALB and neoplasm: Chen et al. have fabricated the photosensitizer chlorin e6 (Ce6), and the chemotherapy drug paclitaxel (PTX) co-loaded human serum albumin (HSA) nanoparticles with cRGDyK peptide modification (Figure 2B), which were able to target tumor angiogenic endothelium overexpressing αvβ3-integrin and exhibited significant antitumor efficacy due to the combined photodynamic/chemotherapy (Chen et al., 2015).
