Due to antibiotic abuse and the emergence of multidrug resistant microorganisms, medical devices and biomaterials are at high risk of microbial infection. Metal-phenolic networks (MPNs), an emerging organic-inorganic hybrid network system, have shown multifunctional properties and excellent antibacterial performance. This review summarizes different categories of biomaterials based on MPNs and their fabrication strategies, and highlights recent advances in their antimicrobial applications in fields such as skin repair, bone regeneration, and medical devices.
Due to the abuse of antibiotics and the emergence of multidrug resistant microorganisms, medical devices, and related biomaterials are at high risk of microbial infection during use, placing a heavy burden on patients and healthcare systems. Metal-phenolic networks (MPNs), an emerging organic-inorganic hybrid network system developed gradually in recent years, have exhibited excellent multifunctional properties such as anti-inflammatory, antioxidant, and antibacterial properties by making use of the coordination between phenolic ligands and metal ions. Further, MPNs have received widespread attention in antimicrobial infections due to their facile synthesis process, excellent biocompatibility, and excellent antimicrobial properties brought about by polyphenols and metal ions. In this review, different categories of biomaterials based on MPNs (nanoparticles, coatings, capsules, hydrogels) and their fabrication strategies are summarized, and recent research advances in their antimicrobial applications in biomedical fields (e.g., skin repair, bone regeneration, medical devices, etc.) are highlighted.
