Traditionally based on gold nanoparticles (AuNPs) for visual detection, recent advances in nanotechnology have expanded the LFIA toolkit to include a wide range of nanoparticles (NPs), such as carbon NPs, quantum dots, upconversion NPs, nanozymes, aggregation-induced emission nanoparticles, and bimetallic or hybrid structures. These novel nanomaterials improve assay sensitivity and allow for multimodal detection (using fluorescence, surface-enhanced Raman scattering or photothermal detection). Central to the performance of NP-based LFIAs is the protein corona, typically formed by antibodies, which mediates antigen recognition. Immobilization strategies range from simple physisorption to more controlled chemisorption techniques (e.g., 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxysuccinimide carbodiimide coupling, thiol- or glycan-directed attachment) and bioaffinity methods (e.g., biotin–streptavidin). Although chemisorption is often assumed superior, a critical comparison of recent studies reveals that optimized physisorption can achieve similar or better detection limits in many cases. Conjugation strategy, NP morphology, and surface chemistry collectively influence probe stability, orientation, and binding efficiency. This review critically evaluates recent innovations in nanoparticle selection, conjugation methods, and signal generation strategies.</div></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"80 ","pages":"Article 101968"},"PeriodicalIF":7.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145358854","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}

Electrically conductive foams are fabricated by incorporating conductive fillers or additives, and these materials need to be designed so as not to affect the stability of the emulsion. The key to successful emulsion-based functional foams lies in achieving a synergistic combination of the inherent advantages of the emulsion and the specific roles of functional additives.

In the broadest sense, oleogel emulsions can be structured by dispersing oleogels in water or vice versa, stabilized by interfacially adsorbed food-grade particles or entangled network structures that retard droplet–droplet coalescence and phase separation. This review aims to provide an up-to-date overview of various oil-structuring approaches, highlighting their properties, different types of oleogel-structured emulsions, and the stabilization mechanisms involved in the formation of oleogel emulsions. Specifically, the factors affecting the characteristics of oleogel emulsions are summarized, including oil types, oil/water ratios, oleogelators, emulsifiers, and processing parameters. Additionally, recent studies on the application of oleogel emulsions in food products are discussed. Currently, there are three main mechanisms responsible for stabilizing oleogel emulsions: Pickering particles, network stabilization, or a combination of both. The droplet size, physical stability, and rheological properties of oleogel emulsions are strongly influenced by the nature and concentration of the oleogelators used as they gel the oil phase, which helps achieve the desired thermomechanical and microstructural properties. Similarly, changes in the type of oils or oil/water ratios used directly impact the physicochemical properties of the systems.
