Preparation and characterization of PEM-ARM. A Schematic diagram of the preparation process of PEM-ARM. B Protein composition analyses of RBCm, Lip-ARM and PEM-ARM using SDS-PAGE. C Representative TEM images of Lip-ARM, EM-ARM, and PEM-ARM; erythrocyte membrane (blue arrow), scale bar: 100 nm. D Mean diameter and zeta potential of Lip-ARM, EM-ARM, and PEM-ARM. Data points represent mean ± s.d. (n = 3). E Stability of liposomes in water (n = 3). F Relative particle size and G relative turbidity in 10% serum of liposomes (n = 3)
