Plasmonic MXene/Au@Ag core–shell heterostructures: a unified platform for electromagnetic stealth, antimicrobial action, and environmental remediation

release and light-triggered ROS generation, alongside >90% adsorption capacity for organic pollutants through MXene's functionalized surface. By unifying electromagnetic stealth, antimicrobial action, and environmental remediation, this work establishes a versatile platform for next-generation composites in aerospace, biomedical, and environmental engineering.
