Schematic illustration of the fabrication process of iRGD-modified RBC membrane-coated mesoporous silica nanoparticles. (A) Synthesis of mesoporous silica nanoparticles (MSNs) and preparation of doxorubicin-loaded nanoparticles (DOX/MSNs); (B) Preparation of iRGD-inserted RBC membrane vesicles; (C) The fusion of DOX/MSNs and iRGD-RBC vesicles to prepare iRGD-RM-(DOX/MSNs).
