Although antibiotic is still the main choice for antibacteria both in hospital and community, phototherapy has become a possibly one of the alternative approaches in the treatment of microbe‐associated infections nowadays because of its considerable potential in effective eradication of pathogenic bacteria. However, overwhelming reactive oxygen species (ROS) generated from phototherapy inevitably...
Double Perovskites
In article number 2305219, Youwen Long, Runze Yu, and co‐workers report the high‐pressure synthesis of a Pb2CoMoO6 double perovskite oxide and unprecedently find antiferroelectricity‐induced negative thermal expansion during the antiferroelectric transition as well as the antiferroelectric phase itself in a wide temperature range across the room temperature.
Materials with negative thermal expansion (NTE) attract significant research attention owing to their unique physical properties and promising applications. Although ferroelectric phase transitions leading to NTE are widely investigated, information on antiferroelectricity‐induced NTE remains limited. In this study, single‐crystal and polycrystalline Pb2CoMoO6 samples are prepared at high pressure...
Tissue Regeneration
In article number 2304324, Yi Deng, Kunneng Liang, and co‐workers report the innovative P‐N bio‐heterojunction (bio‐HJ) material with infection‐primed H2S liberation. In this system, fast sterilization is achieved through the self‐built‐in electric field intensified photodynamics therapy and photothermal therapy. Meanwhile, H2S generated in situ from bio‐HJs accelerates revascularization...
Photodynamic therapy (PDT) acts as a powerful weapon against infectious diseases for its enormous antimicrobial activity that quickly elicits storms of reactive oxygen species (ROS). Nevertheless, redundant ROS during treatment inevitably bring detriments in revascularization. To address this dilemma, an innovative P‐N bio‐heterojunction (bio‐HJ) material consisting of p‐type copper sulfide (p‐CuS),...
Diabetic infectious micromilieu (DIM) leads to a critical failure rate of osseointegration by virtue of two main peculiarities: high levels of topical glucose and inevitable infection. To tackle the daunting issue, a bioheterojunction‐engineered orthopedic polyetheretherketone (PEEK) implant consisting of copper sulfide/graphene oxide (CuS/GO) bioheterojunctions (bioHJs) and glucose oxidase (GOx)...
The integrity of collagen matrix structure is a prerequisite for effectively inducing biomimetic remineralization. Repeated low pH stimulation activates matrix metalloproteinases (MMPs) in dental caries. Activated MMPs cause the breakdown of collagen fibrils. Collagen stabilization is a major obstacle to the clinical application of remineralization templates. Here, galardin‐loaded poly(amido amine)...
For quick disinfection treatment, phototherapy, including photothermal therapy and photodynamic therapy, has emerged as a promising alternative to conventional methods. However, the bactericidal effect of phototherapy, which only works upon light, is short‐lived. The remaining bacteria in situ may repopulate when the irradiation of light is withdrawn. To address this refractory concern, an antibacterial...
Phototherapy has recently emerged as a competent alternative for combating bacterial infection without antibiotic‐resistance risk. However, owing to the bacterial endogenous antioxidative glutathione (GSH), the exogenous reactive oxygen species (ROS) generated by phototherapy can hardly behave desired antibacterial effect. To address the daunting issue, a quad‐channel synergistic antibacterial nano‐platform...
