Although hydrogels demonstrate favorable biocompatibility, their limited mechanical strength and absence of inherent antibacterial properties have restricted their applications. This study presents a novel polyelectrolyte-induced hydrogel coating for UCs, which integrated silver nanoparticle (AgNP)-loaded alginate (SA)-chitosan (CS) microcapsules (AgNPs@(SA-CS) 5 , referred to as AgSC) within a polyvinyl alcohol (PVA)-polyacrylic acid (PAA)- [2-(methacryloyloxy) ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SBMA) (PPMA) hydrogel matrix. The AgSC microcapsules were synthesized through a layer-by-layer assembly of alginate and chitosan, followed by AgNPs loading and template removal, facilitating sustained antibacterial release. The resulting AgSC-PPMA hydrogel was securely immobilized onto polydopamine-modified UCs (AgSC-PPMA@PUCs). The AgSC-PPMA hydrogel coating exhibited exceptional mechanical properties (storage modulus ∼30,780 Pa; tensile strength 0.16 MPa; toughness 33.71 MJ m −3 ), ultra-low friction (coefficient of friction of 0.014 ± 0.001, which was 1/64 that of pristine UCs), high hydrophilicity (water contact angle 24.3 ± 2.4°), and sustained antibacterial activity (>99.99% against E. coli , K. pneumoniae , and P. aeruginosa ; inhibition zone of 16.0 ± 1.4 mm against E. coli , retained at 13.0 mm after 60 d of thermal aging). Furthermore, the AgSC-PPMA@PUCs demonstrated significant antibiofouling properties (protein adsorption: 7.76 ± 2.86 μg cm −2 ), resistance to bacteria-protein complex adhesion, and excellent biocompatibility (cell viability >70%; hemolysis rate <2%). The AgSC-PPMA@PUC represents a highly promising strategy for preventing CAUTIs, combining enhanced durability, superior lubrication, and robust infection resistance in next-generation medical devices. • Polyelectrolyte-induced crystalline domains significantly enhance hydrogel strength. • Ag-microcapsules enable over 99.99% antibacterial efficiency with 60-day longevity. • The hydrogel coating exhibits ultra-low friction and highly hydrophilic properties. • Protein adsorption of less than 7.8 μg cm −2 and a 66.8% reduction bacterial adhesion. • Clinical safety: cell viability over 70% and hemolysis less than 1%.","PeriodicalId":18353,"journal":{"name":"Materials Today Chemistry","volume":"53 1","pages":"103490-103490"},"PeriodicalIF":0.0,"publicationDate":"2026-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147655964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
