Evolving demands for healthier and more sustainable foods require reformulating ingredients and innovating production processes while maintaining sensory quality and shelf-life. Because traditional physics-based models struggle with the multi-scale complexity of food colloids, machine learning (ML) has emerged as a powerful alternative for predicting the behavior of these systems, in which dispersed components critically shape texture and functionality. This article highlights recent ML applications to enhance colloidal stability and rheological properties, demonstrating how supervised and unsupervised algorithms can capture complex, nonlinear relationships. Key examples include neural networks and chemometric models that predict emulsion stability, monitor microstructures, and forecast gel strength. We further discuss how ML-driven approaches reduce time-consuming experimental work and accelerate product innovation. Looking ahead, future opportunities lie in leveraging larger datasets, adopting inverse design strategies, and implementing insights from adjacent fields to deliver the next generation of data-informed, functional food colloids.

The response of molecules to light can have a dramatic impact on the stability, morphology, and controlled release from emulsions or dispersions. In this review, we discuss the underlying mechanisms enabling light-responsive behaviour, including photoswitching, photodestruction, and photothermal effects, in surfactant- and particle-stabilised emulsions and dispersions of structured lipid nanoparticles. We critically evaluate the recent literature to demonstrate the precise control that can be achieved over a wide range of parameters, including droplet size, stability, and release. Finally, we summarise the emerging applications of these systems, identify current challenges, and suggest future research directions.

Hydrogel shells enable precise compartmentalization of aqueous cores while regulating transmembrane molecular transport based on size- and charge-selectivity. Recent advances in droplet microfluidics have enabled the production of monodisperse multiple-emulsion droplets, which serve as ideal templates for hydrogel shell fabrication. This mini-review highlights recent progress in microfluidic emulsion templating for hydrogel shell production and explores optimal design strategies for diverse applications. Hydrogel shells are fabricated using various types of emulsions, with formation mechanisms and material selection tailored to each type. Their applications span drug and cell microcarriers, microreactors, and microsensors, where the composition, structure, and crosslinking density are precisely engineered.

The development of realistic 3D cell culture models by using emulsions and capillary suspensions based on aqueous two-phase systems (ATPS) has advanced the areas of cell physiology and biology. It has shown the potential to enhance the fields of cancer research, biotechnology, rapid testing of drug efficiency and toxicity, tissue engineering, as well as regenerative medicine. It has been increasingly accepted that 3D cells culture more closely reflects normal cellular function due to the enhanced cell interactions, which mimic the in vitro microenvironment and architecture of natural organs and tissues. In this review, we discuss the ATPS-aided methods to form 3D cell spheroids and cell networks by using colloids as templates for the purposes of cell structuring and will discuss the limitations and the advantages of these approaches. The use of ATPS-based cell spheroids has helped to advance basic cell sciences, including understanding cancer cell interactions with their environment in solid tumors, creating better drug models and studying cancer metastasis. Such multi-cellular assemblies have also been applied for engineering tissue constructs which have great potential for studying cell interactions in biological systems under a more realistic in vitro environment compared to 2D cell culture.

The impact of micro- and nanosized plastic particles on the mobility of organic contaminants in the environment is a topic of ongoing scientific debate. Their extensive surface area and capacity to interact with organic contaminants have led to frequent concerns that micro- and nanoplastics significantly enhance their mobility and facilitate contaminant uptake by marine biota. For terrestrial systems, this hypothesis has been adopted, raising concerns that plastic particles could facilitate the transport of contaminants into deeper soil layers, thereby posing a threat to groundwater resources, especially in agricultural soils. These soils receive substantial plastic input through various sources, such as organic soil amendments, mulch, recycled wastewater, and atmospheric deposition. This review examines the molecular interactions between organic contaminants, including a wide range of non-intentionally added substances and additives, and plastic interfaces. We critically analyze the role of micro- and nanoplastics as vectors for contaminants in both marine environments and agricultural soils. Our analysis suggests that the vector effect of contaminants via micro- and nanoplastics in the marine environment is generally insignificant compared to other exposure routes. Our calculations regarding the mass transfer of common plastic additives indicate that the role of micro- and, particularly, nanoplastics as carriers for the majority of organic contaminants in agricultural soils is limited due to rapid desorption rates. Although micro- and nanoplastics do not considerably contribute to transport phenomena as vectors, it is crucial to recognize that they are significant sources of potentially harmful contaminants. These issues must be addressed in the forthcoming INC-5 plastic treaty.

Cellulose nanofibers (CNFs) have been extensively studied as natural stabilizers and emulsifiers for oil-in-water Pickering emulsions (PEs). While wood has been the primary source of CNFs worldwide, agricultural and food waste (AFW) is an attractive biomass source due to its fast growth and abundance. AFW-derived CNFs share structural similarities with wood-derived CNFs, with comparable emulsifying properties, and have attracted significant attention in food and cosmetics industries. Importantly, developing PEs stabilized by AFW-derived CNFs creates new research opportunities for waste valorization and upcycling into sustainable materials. This review summarizes the latest research of PEs stabilized by AFW-derived CNFs and cellulose nanocrystals.

Raman spectroscopy is a light scattering technique in which a molecule scatters incident light at different wavelengths depending on the chemical structure of the analyte, from a high-intensity laser light source. The Raman scattered light is detected to create the Raman spectrum, which is unique to the chemical compounds present in the sample, acting as chemical fingerprints. Since Raman spectrometers can be coupled to a confocal microscope, the selection of regions of interest and a high magnification of the image of the sample can be achieved. Furthermore, 2D and 3D mapping can be generated from thousands of Raman spectra acquired from different positions on the sample, showing the distribution of individual chemical components in the sample. This review summarizes recent advances in the application of confocal Raman spectroscopy to the physicochemical and analytical characterization of microemulsions and nanoemulsions, focusing primarily on topical formulations and biological studies (in-vitro and ex-vivo), and including representative in-vivo and clinical investigations. Identification, quantification, and distribution of components (surfactants, oil phase, active ingredients, etc.) in the colloidal systems, as well as to biological studies related to dynamic processes of formulations in different tissues, even in real-time, were performed. The methodological aspects of confocal Raman spectroscopy in recent works were adequately described, discussed, and compared. Also, we analyzed the limitations and advantages of the spectroscopic technique, including its contribution to green chemistry. Finally, we discuss future perspectives considering its combination with chemometric and artificial intelligence algorithms to improve the quality of the results.

Oleogel emulsions, a hybrid system combining oleogelation and emulsification, have emerged as a groundbreaking innovation in colloidal science, providing sustainable and healthier alternatives for food formulation. 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. These structured emulsions have been widely used as fat substitutes in various food products such as ice cream, cakes, spreads, sausages, margarine, burgers, and peanut butters.

The reduction in wettability afforded by applying superhydrophobic coatings onto substrate materials imbues many useful properties. This review presents recent research advancements of superhydrophobic surfaces formed from functionalised nanoparticles in some of their most promising applications. Silica and metal oxide nanoparticles can be readily functionalised with commercially available hydrophobic compounds to lower their surface energy and can be easily applied to materials with complicated forms and topographies using methods such as spraying or dipping, thus making the coating process adaptable to many situations. Advances in these coatings for imbuing icephobicity, corrosion resistance, self-cleaning, oil-in-water separation, and anti-biofouling behaviour are presented in this short review.
