Physicochemical characterization of RVG/TPP-RSV NPs@RBCm. (A) Particle size and (B) zeta potential distribution of RVG/TPP-RSV NPs@RBCm. (C) Morphological appearance of RVG/TPP-RSV NPs@RBCm based on TEM. (D) In vitro release of RSV from RSV-loaded formulations at pH 7.4 at 37 °C. The data are presented as the means ± SD (n = 3). (E) Stabilities of RVG/TPP NPs@RBCm respectively in PBS and DMEM containing 10% FBS at 37 °C for 60 h. The transmission profiles were measured at each time point using a Turbiscan Lab® Expert analyzer.
