Solar-driven interfacial evaporation is an efficient approach to addressing water scarcity due its environmental sustainability. However, the prolonged use of solar evaporators causes microbial contamination from wastewater. Inspired by antifouling properties polydopamine, we develop a series mono- and dual-metal-loaded poly(norepinephrine) (PNE) nanoparticles pre-doping multiple metal ions. Metal doping enhances photothermal conversion efficiency (∼60%) PNE reducing energy bandgap imparts antimicrobial properties. Cu

Abstract Reactive oxygen species (ROS) play a pivotal role in wound healing due to their ability eradicate bacterial infections. However, excessive ROS can induce oxidative stress and prolonged inflammation, which significantly hinder the wound‐healing process. To address this challenge, Ti 3 C 2 T x ‐Se NPs (TS) heterojunction nanosheets, are developed enhance electron transfer under near‐infrared (NIR) laser irradiation confirmed by ultraviolet photoelectron spectroscopy (UPS) analysis. Compared , TS exhibits superior antibacterial activity against S. aureus E. coli through synergistic mechanisms of chemical dynamic therapy (CDT) photothermal (PTT). In absence treatment, demonstrates “ROS modulating effect”, effectively scavenging catalase (CAT) superoxide dismutase (SOD) activities. efficiently eliminated hydroxyl radicals (90.87%), anion (76.33%), hydrogen peroxide (95.72%) at low concentration, thereby minimizing damage. vivo studies further reveal that reduces damage, clears infections, promotes angiogenesis, accelerating healing. offers precise regulation while leveraging effects PTT CDT. This material not only potent properties but also alleviates accumulation, mitigates fosters tissue regeneration, making it promising candidate for treatment infectious wounds.
