Photocatalytically Activated Cu-N₁S₃ Single-Atom Nanozyme: Enhancing Enzyme Activities and Antibacterial Synergy for Highly Efficient Fruit Preservation.

ABSTRACT: Postharvest preservation urgently demands innovative solutions bridging atomic precision with practical scalability. Here, a distinctive photocatalysis-driven self-assembly strategy is presented that fundamentally diverged from conventional high-temperature syntheses by enabling precise single-atom coordination under ambient conditions. This approach, utilizing α-lipoic acid (α-LA) as coordination ligand, achieved the mild assembly of S-coordinated Cu single-atom nanozymes (Cu/CNS) while significantly enhancing their enzymatic activity. The resulting material demonstrated unprecedented multi-enzyme mimetic activities (catalase-, oxidase-, and glutathione oxidase-like) with catalytic efficiency surpassing conventional nanozymes by orders of magnitude. The Cu/CNS exhibits near-perfect antimi
