Surface-Engineered Carbon Dots as Green and Efficient Nanoscavengers with Dual Protective Functions against Oxidative Stress

Abstract

Biomass-derived carbon dots (TP-CDs) with high-efficiency and antioxidative activity were developed via synergistic core–surface engineering. The TP-CDs integrate phenol–quinone redox chemistry with enzyme-like catalytic radical scavenging, thereby conferring dual protective effects against oxidative stress in cellular and zebrafish models.
