Ruthenium complexes are used as representative photoactive systems, and clinical strains of <i>Pseudomonas aeruginosa</i>, <i>Staphylococcus aureus</i>, and <i>Escherichia coli</i> serve as bacterial targets. Two complementary strategies are deployed in parallel within a single design framework: free-radical copolymerisation of acrylic ruthenium–photosensitiser monomers, and post-polymerisation modification of a pentafluorophenyl-acrylate precursor with amine-functionalised ruthenium complexes. Both routes allow independent tuning of composition, solubility, amphiphilic balance, and net charge, a set of properties that together govern the polymers' interaction with bacterial surfaces. The approach yields a library of seven water-dispersible, amphiphilic polymer–metal hybrids. Benchmarked against a bare ruthenium complex, the aPDT-polymers exhibit strong UV–visible absorption, efficient reactive oxygen species production, low (photo)cytotoxicity towards human bronchial epithelial cells, and potent antibacterial activity, particularly against multidrug-resistant <i>P. aeruginosa</i> in planktonic and biofilm states. Multivariate clustering reveals clear guidelines for structure–activity relationships: anionic acrylic-acid-rich architectures are most effective against <i>P. aeruginosa</i> biofilms under saline conditions, while cationic compositions are preferential against planktonic <i>S. aureus</i>. The platform thus provides a rationally tuneable basis for next-generation polymer-based photoactive antimicrobials.</p>","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":"47 21","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/marc.70426","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148928452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tissue adhesives offer atraumatic sealing, yet conventional adhesive formats and curing modes, including thermal initiation, pH-triggered gelation, and preformed patches, often struggle to combine precise control with physiological compatibility. Photoinitiated adhesives enable on-demand initiation of the curing process via external light-triggered in situ polymerization after tissue apposition and positional adjustment, affording active control over crosslinking density and network architecture, while offering the prominent advantages of mild curing conditions, high spatiotemporal precision, and the absence of deleterious byproducts. This review systematically examines the photochemical mechanisms and application suitability of photoinitiating systems, covering the design principles of Type I cleavage, Type II hydrogen abstraction/electron transfer, and cationic photogenerated acid, as well as visible light-sensitized and near-infrared-assisted activation strategies. From a materials engineering perspective, this review further consolidates the construction strategies, adhesion-enhancing mechanisms, and applications of polyethylene glycol-based synthetic systems, photofunctionalized natural polymer systems, mussel-inspired interfacial systems, and multi-network structural systems.

Herein, we developed a new strategy to regulate the dynamic properties of Knoevenagel condensation (KC) reaction cross-linked hydrogels through reversible thia-Michael addition reaction. In this system, the dynamic C═C bonds formed by the reversible KC reaction could react with thiols via the reversible Michael addition reaction, leading to the structural changes from C═C to C─C bonds and thereby enabling effective modulation of the hydrogel's viscoelastic behaviors. Furthermore, decreasing the pH reduced the reverse reaction rates of both the KC reaction and the thia-Michael addition reaction, reinforcing the stability of the C═C bonds and thia-Michael adducts. To implement this dual regulation, N-acetylcysteine, a small molecule containing both thiol and carboxyl groups, was introduced, which allowed synergistic modulation through thiol-C═C reversible addition and pH responsiveness. This cooperative regulation enables fine-tuned control of hydrogel dynamics, extending stress relaxation time from 20 to 1900 s, enhancing the storage modulus from 2205 to 4705 Pa, and improving the structural stability.
