Characterization of AHPP/OVA and surface cationic polymer modified AHPP/OVA. (A) Schematic of OVA-loaded surface cationic polymer modified AHPP/OVA nanoparticles. (B) Loading efficiency of AHPP/OVA and surface cationic polymer modified AHPP/OVA nanoparticle dispersions stored at 37°C. (C) Zeta-potential and particle size of AHPP/OVA, CS-AHPP/OVA, PEI-AHPP/OVA, and εPL-AHPP/OVA. (D–G) SEM of AHPP/OVA, CS-AHPP/OVA, PEI-AHPP/OVA, and εPL-AHPP/OVA. Results were expressed as means ± SEM (n=3). ^a–b Bars with different superscripts differed significantly (P<0.05).
