Near-Infrared-Enhanced Dual Enzyme-Mimicking Ag–TiO2–x@Alginate Microspheres with Antibactericidal and Oxygeneration Abilities to Treat Periodontitis

/NIR system reduced the bacterial load, relieved inflammation, and improved tissue healing. Our work developed a new local prolonged bactericidal and oxygenation system for enhanced periodontitis. Avoiding the usage of antibiotics and nanomaterials, this strategy showed great promise in adjunctive periodontitis treatment and also in other biomedical applications.
