However, their non-specific cytotoxicity limits their clinical application. One interesting strategy to improve cytocompatibility is the incorporation of sugar units into APs. This approach takes advantage of specific interactions between sugars and protein receptors, such as lectins, on the surface of bacteria, potentially allowing for discrimination between different bacterial types. However, there is limited research on how sugar addition to cationic APs affects their selectivity and interactions with lectins. Herein, a library of acrylamide-based cationic glycopolymers is synthesized by a xanthate-supported photo-initiated Reversible Additon-Fragmentation chain Trasnfer (XPI-RAFT) polymerization. Diverse sugars are added to this cationic scaffold by either chain extension with glycomonomers (based on fucose, glucose, mannose, and polyhydroxy acrylamide) or simply by reductive amination (lactose and melibiose). Various analytical techniques are used to probe the interaction of (glyco)polymers with bacteria, membrane models, and lectins. In general, (glyco)polyhydroxy incorporation proves to reduce the hydrophobicity of the cationic APs and consequently enhances hemocompatibility while maintaining the antimicrobial activity. Although sugar-protein-specific recognition may contribute to selectivity, the results demonstrate that electrostatic interaction predominantly drives the binding efficacy of cationic glycopolymers to bacterial membranes.</p>","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 16","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500273","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Frictional forces are commonly studied in two main contexts: (1) static and kinetic friction acting on droplets subjected to lateral forces, and (2) resisting (frictional) forces opposing the motion of advancing or receding liquid contact lines on solid surfaces. While conventional studies assume identical advancing and receding frictional forces for any liquid–solid pair, recent studies have challenged this notion, emphasizing the need for deeper insight into these forces, especially when the solid is rough. This study employs sessile-droplet experiments for <i>unpinned Wenzel</i> (penetrating) states to quantify frictional forces at the triple-phase contact line, revealing an empirical relationship between frictional force ratio and surface roughness. Contact angle (CA) measurements at constant contact-line speeds under negligible viscous effects (Capillary number, <i>Cα</i> < <1) demonstrate that the advancing-to-receding friction force ratio scales <i>solely</i> with Wenzel roughness, being independent of liquid surface tension, viscosity, or chemical composition.

By systematically varying the laser fluence and pulse number, their effects are examined on LIPSS periodicity and, consequently, SERS performance. The results reveal that increasing laser fluence from 0.80 to 1.40 J/cm<sup>2</sup> significantly reduces LIPSS periodicity due to enhanced Surface Plasmon Polaritons (SPPs) excitation and energy redistribution.

The results demonstrate that precisely tuned periodicity and depth of LIPSS significantly enhance SERS signals by optimizing localized electromagnetic fields and plasmonic resonance effects.
