Herein, bimetallic nanozyme‐based biomimetic bio‐cocklebur (GNR@CeO 2 @GNPs) is designed synthesized for diabetic wound management by depositing spiky ceria (CeO ) shells gold nanoparticles (GNPs) on nanorod (GNR) nanoantenna. The plasmonic‐enhanced nanozyme catalysis self‐cascade reaction properties simultaneously boost two‐step enzyme‐mimicking catalytic activity GNR@CeO @GNPs, leading significant improvement in overall therapeutic efficacy rather than mere additive effects. Under glucose activation 808 nm laser irradiation, @GNPs material captures photons promotes transfer hot electrons from GNR GNPs into CeO , realizing “butterfly effect” consuming local glucose, overcoming limited antibacterial efficiency an individual PTT modality, providing substantial reactive oxygen species. In vitro vivo experiments demonstrate material's exceptional antibiofilm against Gram‐negative Gram‐positive bacteria, which reduce promote collagen deposition, facilitate angiogenesis, thereby accelerating healing.
