Summary: Peri-implant infection is a significant challenge in the clinical field. Researchers are developing biomaterial and bioengineering-based antimicrobial strategies to tackle this issue. However, the development of these approaches is hindered by challenges like biocompatibility concerns, reduced antimicrobial effectiveness, long-term stability issues, and antibiotic resistance development. This review provides insights into current state-of-the-art biomaterial-based antimicrobial approaches and highlights the importance of translational research strategies and regulatory frameworks for clinical implementation. The integration of computational tools and experimental databases using artificial intelligence (AI) is proposed as a vision to accelerate the development of next-generation biomaterial-based antimicrobial strategies.

Summary: In this study, the surface decontamination of bacteria by argon atmospheric-pressure plasma jet was systematically investigated. The chemical modifications and etching characteristics of Gram-positive and Gram-negative bacteria were analyzed through in-situ Fourier transform infrared spectroscopy. It was found that etching, rather than chemical modifications, dominates the infrared spectral variations. The etching rate of bacteria is comparable to the cell wall constituents. The destruction of the cellular envelope by plasma etching is identified as the main cause of bacterial inactivation. The limited penetration depth of reactive species into bacterial deposits was also observed.

Summary: The effects of proteins on the corrosion behavior of zinc-based alloys under non-static conditions were investigated. Smaller protein concentrations had a more significant impact during the early stage of metal degradation. The corrosion rate of the Zn-Cu alloy decreased with increasing bovine serum albumin concentrations. A numerical model for the corrosion process under dynamic flowing conditions was established. The results have important implications for the development and application of biodegradable zinc-based biomedical implants.

Summary: In this study, a three-dimensional multi-interface structured zinc phosphate particle with large specific surface area was prepared and applied in the development of a waterborne epoxy resin coating. The results showed that the multi-interface structured zinc phosphate particles improved the corrosion resistance of the coating, as evidenced by the highest corrosion potential, lowest corrosion current density, and the highest low-frequency impedance. Furthermore, the coated samples with the multi-interface structured zinc phosphate particles exhibited minimal changes in electrochemical properties and maintained high adhesion strength even after immersion in salt solution for 3000 hours.
