Abstract Metal-based nanoenzymes with excellent biocompatibility and stable chemical properties are an effective antimicrobial agent against bacterial resistance due to their radical-mediated catalysis. In this work, the pH of most infection sites being close neutral, targeting problem Fe3O4@Ag difficulty in maintaining catalytic activity neutral environments, we prepare a novel multifunctional Fe3O4@Ag@ Indocyanine Green / Adenosine triphosphate peroxidase for synergistic antibacterial activity. ICG (Indocyanine Green) ATP (Adenosine triphosphate) adsorbed on surface through electrostatic adsorption form its structure. The cell viability remained above 90%, indicating good biocompatibility. By complexing participate single electron transfer binding Fe (II), promotes sudden release ·OH from system, successfully transferring extends pH. utilizing as photosensitizer sonosensitizer, under combined treatment near-infrared light ultrasound, photodynamic therapy (PDT) photothermal (PTT) sonodynamic (SDT) functions can be achieved, achieving effects. environment, bactericidal efficiency Gram negative (Escherichia coli) positive (Staphylococcus aureus) is 99.9% 99.7%, respectively, providing new multi-mode strategy infections.

The application of light-responsive nanomaterials (LRNs) in bone tissue engineering shows broad prospects, especially promoting healing and regeneration. With a deeper understanding the mechanisms defects disorders, LRNs are receiving increasing attention due to their non-invasive, controllable, efficient properties. These materials can regulate cellular biological reactions promote cell adhesion, proliferation, differentiation by absorbing specific wavelengths light converting them into physical chemical signals. In addition, unique surface morphology biocompatibility enable effectively load drugs engineering, achieve precise release, optimize regeneration process. Through photothermal photodynamic therapy, these also possess antibacterial properties play an important role repair infectious defects. Although have shown significant advantages regeneration, series challenges still need be overcome widespread effective clinical applications. This article summarizes basic principles, classification, potential applications aiming provide reference for future research

Daily exposure to contaminated environments and surfaces leads serious health issues, increasing healthcare costs. Active materials that act against pathogens can effectively prevent their proliferation contribute increased protection infections. In this contribution, nanostructured thin films containing silver are investigated, using SiO2 TiO2 as transparent matrices embed the Ag atoms. The were obtained via magnetron sputtering, HiPIMS for deposition RF sputtering oxides, in either an Ar or Ar/O2 environment. Atomic Force Microscopy provided information on coating topography films’ preferential growth textured polymer foil, X-Ray Diffraction highlighted structural difference between different versions, Ultraviolet–Visible–Near-Infrared spectroscopy proved optical quality transparency Energy-Dispersive X-ray Spectroscopy revealed composition changes processes. effect of O2 addition is analyzed compared terms induced properties films. Following 24 h incubation a media 104 CFU/mL Escherichia coli, TiO2+Ag sample with showed highest antibacterial effectiveness, indicated by largest inhibition zone. Experiments selective hierarchy efficiency, namely, TiO2+Ag+O2 > SiO2+Ag.
