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...
Wound biofilm infection has an inherent resistance to antibiotics, requiring physical debridement combined with chemical reagents or antibiotics in clinical treatment, but it is invasive and may exist as incomplete debridement. So, a new type of noninvasive and efficient treatment is needed to address this problem. Here, the crystal phase engineering of TiO2 is presented to explore the sonocatalytic...
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...
The richened reactive oxygen species (ROS) and their derived excessive inflammation at bone injured sites hinder osteogenesis of endosseous Ti‐based implants. Herein, anti‐oxidized polydopamine (PDA) is deposited on hydrothermal growth formed hydroxyapatite (HA) nanorods on Ti to form a core‐shell structural nanorod‐like array with HA as a core and PDA as an amorphous shell (PDA@HA), showing not only...
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...
Development of high‐performance and low‐cost nonprecious metal electrocatalysts is critical for eco‐friendly hydrogen production through electrolysis. Herein, a novel nanoflower‐like electrocatalyst comprising few‐layer nitrogen‐doped graphene‐encapsulated nickel–copper alloy directly on a porous nitrogen‐doped graphic carbon framework (denoted as NixCuy@ NG‐NC) is successfully synthesized using...
In article number 1901545, Wenjun Zhang and co‐workers synthesize a novel nanoflower‐like electrocatalyst comprising of few‐layer nitrogen‐doped graphene encapsulated nickel copper alloy on porous graphic carbon framework by a facile and scalable method, and it exhibits high activity and excellent stability for hydrogen evolution.
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...
Photodynamic therapy (PDT) utilizing light‐induced reactive oxygen species (ROS) is a promising alternative to combat antibiotic‐resistant bacteria and biofilm. However, the photosensitizer (PS)‐modified surface only exhibits antibacterial properties in the presence of light. It is known that extended photoirradiation may lead to phototoxicity and tissue hypoxia, which greatly limits PDT efficiency,...
A novel mesoporous nanosheet networked hybrid comprising Co3O4 and Co3(PO4)2 is successfully synthesized using a facile and scalable method through calcinating the carbon, cobalt hydroxy carbonate, and cobalt phosphate composite precursor. Electron transfer from Co3O4 to Co3(PO4)2, together with the special networked structure and the porous nature of the nanosheets enable the Co3(PO4)2‐Co3O4 hybrid...
KOH activation of microwave exfoliated graphite oxide (MEGO) is investigated in detail at temperatures of 450–550 °C. Out of the activation temperature range conventionally used for the preparation of activated carbons (>600 °C), the reaction between KOH and MEGO platelets at relatively low temperatures allows one to trace the structural transition from quasi‐two‐dimensional graphene platelets...
