Characterization of liposomes. (A1) MALDI-TOF-MS spectrum of DSPE-PEG2000-COOH, (A2) MALDI-TOF-MS spectrum of DSPE-PEG2000-PFV, (B) TEM image of targeted daunorubicin and dioscin codelivery liposomes, (C) In vitro cumulative release profile of daunorubicin from varying liposomal formulations. Data are presented as mean ± SD (n=3). △, vs Daunorubicin liposomes; #, vs Daunorubicin and dioscin codelivery liposomes. p<0.05, (D1) AFM image of targeted daunorubicin and dioscin codelivery liposomes, (D2) 3D structure of (D1).
