Droplets impacting solid surfaces are encountered in nature and industry, from rain to agricultural spraying and inkjet printing. Surfactants are an important factor that affects the impact behavior of droplets. An in-depth knowledge of the influence and mechanisms of surfactants on the dynamics of droplet impact can enhance the precise control of droplets in industrial processes. Herein, recent insights into surfactant-enhanced droplet deposition on hydrophobic surfaces are reviewed. First, the mechanisms of surfactant-enhanced droplet deposition are summarized. Second, the factors that influence droplet deposition, such as molecular diffusion, convective diffusion of surfactants, characteristics of hydrophobic surfaces, and interaction between the surfactant-laden droplets and the hydrophobic surfaces, are explored. Additionally, the influences of surfactants on the spreading and retraction processes of impacting droplets, maximum spreading factor, and oscillation dynamics are reviewed. Finally, typical applications of surfactants in different fields, such as inkjet printing, supercooled surface, and agricultural spray, are summarized, along with challenges and prospects in future research, to provide suggestions for subsequent studies.

Pickering emulsions (PEs) are dispersions stabilized by solid particles, which are derived from various materials, both organic (proteins, polysaccharides, lipids) and inorganic (metals, silica, metal oxides). These colloidal particles play a critical role in ensuring the stability and functionality of PEs, making them highly valued across multiple industries due to their enhanced stability and lower toxicity compared to conventional emulsions. The stabilization mechanisms in PEs differ from those in emulsions stabilized by surfactants or biopolymers. The stability of PEs is influenced by intrinsic particle properties, such as wettability, size, shape, deformability, and charge, as well as external conditions like pH, salinity, and temperature. Some particles, especially organic ones, alone may not be effective stabilizers. For instance, many polysaccharides inherently lack surface activity, while most proteins have significant surface activity but often become unstable under environmental stresses, potentially leading to emulsion instability. The chemical composition and morphology of the particles can lead to varying properties, particularly wettability, which plays a vital role in their ability to adsorb at interfaces. As a result, surface modification emerges as an essential approach for improving the effectiveness of particles as stabilizers in PEs. This review presents the mechanisms that stabilize PEs, identifies factors influencing the stability of PEs, and discusses physical and chemical techniques for modifying particle surfaces. There has been a significant advance in understanding surface modification, employing both physical (non-covalent bonds) and chemical (covalent bonds) approaches. These insights are invaluable for optimizing PE formulations, broadening their application potential across various fields.

β-lactoglobulins (βLGs) have a wide range of applications in food because of their ability to emulsify, foam, and gel. This makes them good functional additives. However, their performance depends on temperature, pH, and mineral levels, so their functional qualities are limited in particular applications. How polyphenols (PPs) interact with βLG is crucial for the functional characteristics and quality of dietary compounds. In most food systems, a spontaneous interaction between proteins and PPs results in a “protein-PP conjugate,” which is known to affect the sensory, functional, and nutraceutical qualities of food products. The βLG-PP conjugates can be used to enhance the quality of food. This article emphasizes analytical techniques for describing the characteristics of βLG-PP complexes/conjugates. It also goes over the functions of βLG-PP conjugates, including their solubility, thermal stability, emulsifying, and antioxidant qualities. The majority of βLG-PPs interactions is due to non-covalent (H-bonding, electrostatic interactions) or covalent bonds that are mostly caused by βLG or PP oxidation through enzymatic or non-enzymatic mechanisms. Furthermore, the conformation or type of proteins and PPs, as well as environmental factors like pH and temperature, have a significant impact on proteins-PPs interactions. Higher thermal stability, antioxidant activities, and superior emulsifying capabilities of the βLG-PP conjugates make them useful as innovative additives to enhance the quality and functions of food products.

The interconnected nature of lamellar gel networks (LGNs) imparts, amongst other beneficial properties, unique rheological behaviours and superior stability which make them highly popular for the formulation of cream-based pharmaceutical and cosmetic products, notably hair conditioner. However thus far, little attention has been given to the combined role of formulation and processing techniques in creating an LGN structure. The aim of this review is to provide a comprehensive insight into the effects of formulation, processing conditions and manufacturing equipment on the structure and properties of LGNs, and how these properties might be assessed. Areas of future research for hair conditioner manufacture are identified, including the leveraging of digital tools such as process analytical technology and machine learning for a deeper understanding of product structure under diverse condition. These approaches are a critical step in the development of the next generation of sustainably manufactured formulated products.

Aqueous two-phase system (ATPS) has been of interest to both industry and academia for the extraction and purification of biomolecules/bioactives. ATPSs are formed by two-phase forming components such as polymer-polymer, polymer-salt, surfactant-salt, etc. when dissolved in water above critical concentrations. The binodal curve distinguishes the single-phase region from the two-phase region. These compositions are usually expressed in weight or mole fractions. The binodal curve and tie-lines in the phase diagram are pivotal in the design of extraction experiments, phase separation, and determining the concentration of phase-forming components. An engineered choice of working on a tie-line determines the purity and yield of the extracted compound. Researchers have explored various approaches for the generation of binodal curves including, macroscale, microscale, thermodynamic, and computational methods. Although different methods have been used for the generation of the binodal curves, there is limited information that summarizes these methods comprehensively. This article aims to summarize the different techniques of binodal curve generation for ATPSs, outlining their merits and demerits, along with the applications of ATPSs. Comparison of different methods for the generation of binodal curves is slightly challenging as every method is distinct and unique. In the case of the convenient method, the macroscale approach could be the preferred one, whereas the microscale approach is advantageous for the rapid generation with low volumes of samples. Furthermore, thermodynamic modeling and computational approaches can be preferred for the generation of binodal curves when minimizing experimentation and sophisticated equipment is a priority.

Effective delivery of active substances and drugs is an important part of treatment. In order for a drug to work at the right place in the body, it must be transported there in the right way. For this reason, new carriers are being sought for active substances and drugs that can effectively deliver drugs to the target site without causing additional side effects. These include nanoparticles, microneedles, cubosomes and nanogels, among others. Recently, carriers based on biodegradable polymers such as hyaluronic acid or chitosan are becoming popular. In addition, modern carriers are designed to release the active ingredient in response to a specific agent. This paper reviews the literature from the past 5 years on novel delivery systems with medical, agricultural, food and cosmetic applications, with a special emphasis on the use of carbohydrate-based nanocarriers.

Tissue engineering (TE) involves repairing, replacing, regeneration, or improving the function of tissues and organs by combining cells, growth factors and scaffold materials. Among these, scaffold materials play a crucial role. Silk fibroin (SF), a natural biopolymer, has been widely used in the TE field due to its good biodegradability, biocompatibility, and mechanical properties attributed to its chemical composition and structure. This paper reviews the structure, extraction, and modification methods of SF. In addition, it discusses SF's regulation of cell behavior and its various processing modes. Finally, the applications of SF in TE and perspectives on future developments are presented. This review provides comprehensive and alternative rational insights for further biomedical translation in SF medical device design, further revealing the great potential of SF biomaterials.

Among the many types of surface modifications on porous silicon (pSi), hydrosilylation stands out to be an important approach due to the formation of highly stable surface linkage through Si-C bonding. Since its conceptualization in 1998, hydrosilylation had gradually gained popularity for pSi surface modifications and had become an important approach for stabilizing pSi surfaces especially for biological applications. Over the past decade, significant advancements have been made in the hydrosilylation process for modifying porous silicon (pSi) surfaces. These developments have progressed to the point of enabling the incorporation of multiple chemical functionalities onto a single surface. This review aims to highlight the most recent studies on hydrosilylation of pSi surfaces, explore some of the more unconventional reaction mechanisms available in pSi surface chemistry, and discuss the challenges associated with implementing these strategies.

Nanopore-based electrical detection technology holds single-molecule resolution and combines the advantages of high sensitivity, high throughput, rapid analysis, and label-free detection. It is widely applied in the determination of organic and biological macromolecules, small molecules, and nanomaterials, as well as in nucleic acid and protein sequencing. There are a wide variety of organic polymers and biopolymers, and their chemical structures, and conformation in solution directly affect their ensemble properties. Currently, there is limited approach available for the analysis of single-molecule conformation and self-assembled topologies of polymers, dendrimers and biopolymers. Nanopore single-molecule platform offers unique advantages over other sensing technologies, particularly in molecular size differentiation of macromolecules and complex conformation analysis. In this review, the classification of nanopore devices, including solid-state nanopores (SSNs), biological nanopores, and hybrid nanopores is introduced. The recent developments and applications of nanopore devices are summarized, with a focus on the applications of nanopore platform in the resolution of the structures of synthetic polymer, including dendritic, star-shaped, block copolymers, as well as biopolymers, including polysaccharides, nucleic acids and proteins. The future prospects of nanopore sensing technique are ultimately discussed.
