摘要：

In this study, we developed a method for synthesizing silver nanoparticles (AgNPs) using aqueous assembly assay and anchoring them with camellia seed cake polyphenols (CPs). Zeta potential analysis demonstrated a higher binding affinity of CP-AgNPs to Penicillium digitatum, which could be attributed to the interaction between the hydroxyl group of CP-AgNPs and the polysaccharide present on the fungal cell wall. Compared to AgNPs, the CP-AgNPs outperformed conventional AgNPs in antifungal activity against P. digitatum. The mechanism underlying this antimicrobial effect involves raising the leve...
