With the development of antimicrobial resistance, rapid and effective killing bacteria is required for infected wound healing after skin trauma. Herein, we reported a one-pot reaction strategy to prepare composite hydrogel with antibacterial activity through high-efficiency photothermal therapy. We take poly(vinyl alcohol) as matrix, lignin-derived from biomass was introduced into increase tensile strength prepared 108.58 kPa, elongation at break reaches 200.8%. The electrostatic interaction between lignin chitosan enhanced reactivity lignin. Carbon nanotubes endow that can kill more than 97% either Escherichia coli or Staphylococcus aureus within 5 min, avoiding problem bacterial resistance. Experimental evaluation on mice showed could effectively promote full-thickness defects. hydrogels good mechanical properties, antioxidant activity, excellent ability show potential repair damaged tissue are expected be used in clinical transformation dressing.

One of the challenges posed by current antibacterial therapy is that expanded and massive use antibiotics endows bacteria with ability to resist almost all kinds antibiotics. Therefore, developing alternative strategies for efficient treatment urgently needed. Antibacterial gas has attracted much attention in past decade. Nitric oxide (NO), carbon monoxide (CO), sulfur dioxide (SO2), hydrogen sulfide (H2S), (H2) are not only known as endogenous signaling molecules, but also play critical roles many pathological processes. These gases considered attractive bactericidal agents because they able kill bacteria, disperse biofilms, promote bacteria-infected wound healing while avoiding resistance. In this review, we discuss properties these gases, well recent advances gas-involving systems antibacterial, antibiofilm, applications. Moreover, summarize various donors utilized treatment. We hope review will shed new light on future design applications advanced therapy.

Abstract The rising dangers of bacterial infections have created an urgent need for the development a new generation antibacterial technologies and therapeutics. Antibacterial photodynamic therapy (PDT), considered as noninvasive treatment with no drug resistance, has become promising photochemistry‐involved strategy. Titanium oxide (TiO 2 ) is proved to be very efficient PDT agent among photosensitive materials, while property large bandgap TiO makes it only excited by ultraviolet light, which harmful organisms. In this work, novel ligand‐to‐metal charge transfer (LMCT) mediated strategy proposed via harmless near‐infrared light irradiation. By choosing mussel‐inspired material, polydopamine (PDA) involved in forming mesoporous @PDA nanoparticles (mTiO NPs). catechol groups PDA can attach tightly even colloidal environments, also form LMCT bridge, exciting exert function 808 nm Combining sonodynamic (SDT) photothermal properties PDA, simple structure mTiO enables synergistic applications multiple functions under dual excitation NIR ultrasound. This reliable all‐in‐one NPs achieve great effect rapid repair infected wounds.
