The advent of the COVID-19 pandemic has underscored pressing demand for antimicrobial materials that offer both durability and efficacy. Herein, successful design fabrication a "water-insoluble" supramolecular precipitate is reported through "bottom-up" assembly polyanion sodium alginate (SA) with motifs A2G Cu2+. This innovative hetero-motif polyionic junction leverages network hydrogen bonds aligning electrostatic interactions, hydrophobic effects to mitigate rapid release active components, providing exceptional long-term efficacy against Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Candida albicans (C. albicans). Specifically, it retains an impressive 99.9% S. even after enduring 10 successive wash cycles. hydroxyl groups in A2G-Cu-SA confer adhesion wide array substrates. robust adherence complemented by its antibacterial properties, material maintaining rate being submerged water extended period 100 days. In vivo vitro studies substantiate biocompatibility A2G-Cu-SA, while clinical potential evidenced enhanced healing aureus-infected wounds upon titanium sheet coating. innovation meets current need effective antimicrobials contributes sustainable medical advancements.
