Quantitative analysis confirmed a clear relationship between electrospinning conditions and fiber alignment. The membranes displayed stable degradation characteristics suitable for biomedical applications. Notably, highly aligned PPDO membranes promoted spindle-shaped cellular morphology and enhanced secretion of three growth factors- alpha-smooth muscle actin (α-SMA), basic fibroblast growth factor (bFGF), and transforming growth factor-beta 1 (TGF-β1), facilitating favorable cellular responses for regeneration.

In this study, we proposed a low-risk strategy to introduce eugenol into Stöber silica nanoparticles through a copper-mediated synthesis route. The goal was to produce a eugenol-based organosilane and use it as a chemical modifier agent. This approach seemed to be useful for overcoming the difficulties associated with introducing active compounds into Stöber silica nanoparticles because of their low/absent porosity, while avoiding harmful reactants. The eugenol-based organosilane was included in silica nanoparticle synthesis after a period longer than the established induction period to avoid possible disruptions in the colloidal system, which could drive noncontrolled aggregation events. According to the dynamic light scattering measurements, the particles became larger (diameter: 109.8 nm; 145.5 nm) as more eugenol-based modifier was added (1 %; 20 %), possibly due to its incorporation as hydrolyzed species onto the already-formed silica particles (from the monomer-addition perspective). In addition, thermogravimetric analysis of the modified silica nanoparticles revealed that the thermal decomposition peak, assigned to the organosilane, was more intense in formulations to which higher amounts of eugenol-based modifier were added, indicating the occurrence of the modification. Finally, the inhibitory effects of the eugenol-modified silica nanoparticles on <em>Aspergillus niger</em> colonies confirmed the presence of the eugenol-based organosilane in the silica nanoparticles as well as the maintenance of the antifungal properties of eugenol when supported.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"724 ","pages":"Article 137501"},"PeriodicalIF":4.9,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144298526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system leverages centrifugal force-driven fluid dynamics and machine learning-enabled detection to achieve precise control over monodisperse droplet formation. Through integration of multifaceted parameter optimization—encompassing capillary geometry, rotational kinematics, and interfacial properties—the platform exhibits robust operational stability and tunable droplet dimensions, thereby offering distinct advantages over conventional microfluidic approaches constrained by fixed geometries and pump-induced instabilities. A deep learning-based detection framework, enhanced with Hough circle optimization, enables high-precision droplet characterization with sub-1 % measurement accuracy, establishing a foundation for closed-loop process control. The CCAP’s versatility is further validated through the successful construction of biphasic W/O and O/W systems and the synthesis of functionalized magnetic porous trimethylolpropane triacrylate (TMPTA) particles. These particles exhibit exceptional catalytic performance in degrading organic pollutants such as methylene blue, achieving rapid pollutant removal while maintaining robust recyclability.
