Anodic aluminum oxide (AAO) films have a wide range of research and applications in the field nanoscience technology. Transparent AAO require layer to be peeled off from substrate which it is attached, involving complex preparation process immersion variety caustic solutions, resulting prepared that are very prone fragmentation unfavorable for applications. Here, we transparent by double-sided anodization method with secondary anodization, consists porous structure spaced barrier layer. These can bent into bow shape exhibit good toughness under action external forces applied at both ends. Then, were subjected thermal shock experiments, changes microstructure before after analyzed. The relationship between they was also investigated.

Implant-associated infections and excessive immune responses are two major postsurgical issues for successful implantation. However, conventional strategies including antibiotic treatment inflammatory regulation always compromised due to the comodification of various biochemical agents instances functional interference. It is imperative provide implant surfaces with satisfactory antibacterial anti-inflammatory properties. Here, a dual-effect nanostructured polyetheretherketone (PEEK) surface (NP@PDA/Zn) bionic mechano-bactericidal nanopillars immobilized immunomodulatory Zn2+ designed. The constructed hybrid display remarkable performance against Gram-negative Gram-positive strains through synergy physical chemical bactericidal effects imposed by Zn2+. Meanwhile, immunoregulatory property evaluated investigation macrophage polarization both in vitro vivo, results reveal that NP@PDA/Zn could downregulate expression M1-related cytokines decrease M1 recruitment lower response. Notably, exhibited exceptional biocompatibility discerning biocidal activity between bacterial mammalian cells antioxidant effectively scavenges ROS, minimizing potential cytotoxicity. Taken together, presents convenient promising strategy combining synergistic without any mutual interference, which can support development multifunctional implant-associated materials.

Postcharging antibacterials have shown good application prospects in combating bacterial infections through electrical interaction. Herein, manganese oxide nanosheets situ grown on carbon fibers (CM) are designed to perform the integration of mechanical intervention and postcharging therapy for efficient killing. This electrode disrupts membranes via sharp-edged microstructures. After charging at a low voltage an ultrashort time, charged CM affects extracellular electron transfer (EET) bacteria during discharge process kill bacteria. Due dual-antibacterial mode, after −1 V (vs saturated calomel electrode, SCE) only 50.4 ± 3 s, lethality rates against Escherichia coli Staphylococcus aureus within 0.5 h both exceed 98%. Our developed ultrafast negatively exhibits high antibacterial activity cytotoxicity fibroblast cells, providing non-antibiotic approach combat infection.
