Bacteria‐induced epidemics and infectious diseases are seriously threatening the health of people around the world. In addition, antibiotic therapy has been inducing increasingly more serious bacterial resistance, which makes it urgent to develop new treatment strategies to combat bacteria, including multidrug‐resistant bacteria. Natural extracts displaying antibacterial activity and good biocompatibility...
The ability to effectively treat deep bacterial infections while promoting osteogenesis is the biggest treatment demand for diseases such as osteomyelitis. Microwave therapy is widely studied due to its remarkable ability to penetrate deep tissue. This paper focuses on the development of a microwave‐responsive system, namely, a zinc ion (Zn2+) doped graphite carbon nitride (CN) system (BZCN), achieved...
Defect engineering is an important way to tune the catalytic properties of metal‐organic framework (MOF), yet precise control of defects is difficult to achieve. Herein, a cerium‐based MOF (CeTCPP) is decorated with Au nanoparticles. Under ultrasound irradiation, Au nanoparticles can precisely turn 1/3 of the pristine Ce3+ nodes into Ce4+. With the stable existence of Ce4+, the coordination of Ce...
It is difficult to effectively treat bacterial osteomyelitis using photothermal therapy or photodynamic therapy due to poor penetration of light. Here, a microwave (MW)‐excited magnetic composite of molybdenum disulfide (MoS2) / iron oxide (Fe3O4) is reported for the treatment of bacteria‐infected osteomyelitis. In in vitro and in vivo experiments, MoS2/Fe3O4 is shown to effectively eradicate bacteria‐infected...
Pathogenic bacteria that adhere on the surface of textiles, especially healthcare workers’ uniforms, have brought severe problems, including nosocomial infection and other infectious diseases. Here, antibacterial textiles are fabricated by in situ growing oxygen vacancies (OVs) BiOBr on the surface of Ti3C2 nanosheets followed by in situ polymerization of polypyrrole (ppy). The formed Schottky heterojunction...
One of the most difficult challenges in the biomedical field is bacterial infection, which causes tremendous harm to human health. In this work, an injectable hydrogel is synthesized through rapid assembly of dopamine (DA) and folic acid (FA) cross‐linked by transition metal ions (TMIs, i.e., Zn2+), which was named as DFT‐hydrogel. Both the two carboxyl groups in the FA molecule and catechol in polydopamine...
Developing in situ disinfection methods in vivo to avoid drug‐resistant bacteria and tissue toxicity is an urgent need. Here, the photodynamic and photothermal properties of the chitosan‐assisted MoS2 (CS@MoS2) hybrid coating are simultaneously inspired to endow metallic Ti implants with excellent surface self‐antibacterial capabilities. This coating, irradiated by only 660 nm visible light (VL) for...
