Preparation, Characteristics, and Formation Mechanism of Oyster Peptide-Zinc Nanoparticles

Oyster peptide-zinc nanoparticles (OPZNPs) (28–108 nm) were prepared in the presence of 0.5%–0.9% zinc sulfate at pH 6.0–11.0. The obtained nanoparticles exhibited uniform size distribution and spherical shapes. Nanoparticle characteristics, such as size, surface charge, and hydrophobicity, could be adjusted by controlling zinc sulfate concentration and environmental pH. Increasing pH value or decreasing zinc sulfate concentration tended to...
