Apoplast-Confined Nanozyme Catalysis for Selective 1O2 Generation and Host Defense in Plants.
Reactive oxygen species (ROS)-based antimicrobial strategies in plants are often constrained by limited oxidant selectivity and collateral phytotoxicity. Here, we report an apoplast-confined nanozyme that integrates selective singlet oxygen (1O2) catalysis with host defense activation. The copper-iron Prussian blue ana...
