Scanning electron micrographs of (A–C) ovalbumin (OVA)-loaded and (D–F) murabuted-loaded acetalated dextran (Ace-DEX) microparticles (MPs) of different relative cyclic acetal coverage (CAC): (A, D) 20%, (B, E) 40%, and (C, F) 60%. (G) Empty MPs were fashioned from 40% Ace-DEX polymer. Scale bars are 5 μm.
