(A) Circulation time of NLVs@MNPs/DOX, NPVs@MNPs/DOX and RGD-NPVs@MNPs/DOX in mice bearing MDA-MB-231/ADR tumors. (B) Fluorescence images of mice bearing MDA-MB-231/ADR tumors at 2 h and 24 h after intravenous injection of NLVs@MNPs/DOX, NPVs@MNPs/DOX and RGD-NPVs@MNPs/DOX. Frozen sections of MDA-MB-231/ADR tumors at 4 h (C) and 24 h (D) after intravenous injection of NPVs@MNPs/DOX and RGD-NPVs@MNPs/DOX. A FITC-tagged CD31 antibody was used to label the tumor vasculature, and DAPI was used to label the nuclei (red signal, RhB; blue signal, DAPI; green signal, FITC). Scale bar represents 300 μm.
