通过对具有不同几何形状和功能的纳米物体进行连续化学接枝，制备了兼具按需光控活性和持续杀菌释放特性的光响应抗菌表面。所开发的多层涂层包含一层由银纳米粒子（AgNP）修饰的近红外活性二氧化硅包覆的金纳米星（GNS）单分子层。这种模块化方法还使我们能够阐明静态和光激活对表面整体抗菌性能的贡献，证明了这两种机制之间显著的协同作用。对浮游细菌和附着在表面的细菌进行的微生物学和成像互补评估，为这些不同但相互协作的效应提供了新的见解。
Photo-responsive antibacterial surfaces combining both on-demand photo-switchable activity and sustained biocidal release were prepared using sequential chemical grafting of nano-objects with different geometries and functions. The multi-layered coating developed incorporates a monolayer of near-infrared active silica-coated gold nanostars (GNS) decorated by silver nanoparticles (AgNP). This modular approach also enables us to unravel static and photo-activated contributions to the overall antibacterial performance of the surfaces, demonstrating a remarkable synergy between these two mechanisms. Complementary microbiological and imaging evaluations on both planktonic and surface-attached bacteria provided new insights on these distinct but cooperative effects.
