ALB and neoplasm: Similarly, Sun et al. reported that encapsulation of doxorubicin-loaded ICG-bovine serum albumin (ICG-BSA) nanocomplex within RGD-modified RBCs could specifically target the nanocomplex to tumor cells, resulting in improved therapeutic efficacy.131 Besides magnetic iron oxide nanoparticles (IONPs), other inorganic nanoparticles can also be loaded in RBCs for improved tumor targeting.
