In the case of chemical heterogeneities, the clustering effect of polar and non-polar groups is assumed to be at the origin of droplet anchoring behavior. Then, on a microscopic scale, the organization of these groups should have an impact on wetting dynamics. As a hypothesis, for an identical surface ratio of two distinct chemistries with the same asperity size, a surface with a chaotic chemical distribution will generate more anchoring than an organized surface. To verify this approach, a numerical model was applied to wetting on textured chemical surfaces. Numerical wetting simulations were developed to simulate wetting in a manner similar to a sessile drop experiment followed by a tilt test. In addition, thanks to the numerical method, it was possible to precisely define different chemical textures, ranging from a totally chaotic texture to an organized one. Dynamic anchoring behaviors were then characterized, for each surface, by the evolution of the triple line velocity during droplet sliding. As a result, the simulations validate the initial hypothesis with the observation of stronger dynamic anchoring during tilting for randomly textured surfaces. This behavior is directly linked to the clustering effect, which creates favorable anchoring sites. It has been shown that this clustering effect also leads to local stick–slip phenomena of the triple line around the droplet.</div></div>","PeriodicalId":10483,"journal":{"name":"Colloid and Interface Science Communications","volume":"70 ","pages":"Article 100871"},"PeriodicalIF":4.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145973031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review evaluates advances in bioinspired surface engineering, emphasizing the comparative performance, material trade-offs, and long-term stability of antifouling and antimicrobial strategies. NMSS reduces the real contact area, increases local shear, and, for dense high-aspect-ratio features, imposes membrane deformation that can cause lysis; bactericidal and antifouling efficacy depends on pillar height, tip radius, spacing, substrate stiffness, and wettability. Multiscale models link nanoscale membrane stresses to mesoscale transport and critical shear thresholds, allowing geometry selection tailored to flow regimes and microbial types. Hybrid strategies that combine topography with benign chemistries (zwitterions, photocatalysts) and stimuli-responsive actuation enhance robustness under protein conditioning and mixed-species biofilms while reducing ecological load.
