Characterization and in vitro release of the rapamycin from the RPLGA nanoparticles. A, Dynamic light scattering analysis for nanoparticles. B, Transmission electron micrograh RPLGA NPs. Bar represents 1 μm. C, Transmission electron microscopic picture of cross-section of VSMCs incubated with NP for 1 hour. Arrows indicate NP in the cytoplasm. Scale bar = 1 μm. D, In vitro release profile of rapamycin from RPLGA NPs. The percentage of rapamycin released was plotted against time.
