Abstract
This study employed the growth curve of selenium nanoparticles (SeNPs) to reveal the mechanism by which Tremella polysaccharides (TP) concentration affects SeNPs. At TP concentrations of 0.25–3.0 mg/mL, TP-stabilized SeNPs (TP-SeNPs) prepared with 1.5 mg/mL TP showed the smallest size (56.8 nm) and optimal stability, as this concentration sufficiently limited the diffusion of Se 0 species and nuclei. The increased particle size (71.8 nm) at 3.0 mg/mL TP was due to TP self-aggregation, evidenced by marked rises in viscosity and hydrodynamic diameter, along with atomic force microscopy-detected aggregates. This aggregation was probably correlated with uronic acid content (17.1%) and the rigid conformation of TP. Thermogravimetry, zeta potential, and storage modulus further confirm that self-aggregation diminishes coating effectiveness. This work provided a theoretical basis for determining stabilizer concentrations in SeNP preparation. Moreover, TP-SeNPs maintained a stable, monodisperse spherical structure under simulated gastrointestinal digestion, showing great potential as a low-toxicity, high-bioavailability Se supplement.
