Abstract
En 中文
• Stepwise hydrothermal fabrication of hierarchical TiO2/CoMn2O4 on Ti alloy. • An “attack-defense” strategy resolves the antibacterial-osteogenesis conflict. • NIR-responsive TiO2 metastructure functions as the “attack” layer for on-demand sterilization. • In-situ CoMn2O4 nanozyme serves as the “defense” layer, scavenging ROS to protect cells. • The surface achieves > 90% antibacterial rate and significantly enhances osteogenesis.
