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.
