Summary: Surfactants are widely used in various industries such as household cleaning, personal care, and cosmetics. However, most of the surfactants currently in use are derived from fossil fuels and are environmentally unfriendly and toxic. Therefore, there is a need for greener alternatives. The determination of the critical micelle concentration of surfactants is crucial for their development as analytical tools and commercial materials. A fast and cost-effective method using dried drop coffee ring image analysis is proposed for determining the surfactant critical micelle concentration.

Summary: This study developed three samples of carbon quantum dots (CQDs) with different fluorescence properties as fluorescent probes for the critical micelle concentration (CMC) determination of surfactants. The CMC values were deduced from the fluorescence intensity change and the Stokes shift variation. The study also found that the interaction between CQDs and surfactant molecules is complicated and the CQDs are located at the palisade layer in the surfactant micelles.

Summary: Lipid oxidation is a major cause of quality deterioration in food products, and the presence of colloidal structures and interfaces play a crucial role in this process. Micelles in emulsions and reverse micelles in bulk oils are reservoirs for antioxidants and pro-oxidants, and serve as nanoreactors where lipid oxidation reactions occur.

Summary: In the autoxidation of rapeseed oil, both water content and phospholipid concentration play important roles in the formation of oxidation products. Amphiphilic substances are crucial in increasing the water content, and water can compensate for the effects of oxidation products on the critical micelle concentration of phospholipids.

Summary: Release of contaminants poses a threat to human health and the environment, and self-assembled nanostructures of nonionic surfactants have shown high efficiency in removing these pollutants. This study evaluates the pollutant-removal efficiency of Brij L4 nonionic surfactant and its self-assembled structures. The interactions between Brij L4 micellar phase and lyotropic liquid crystals and ferrihydrite nanoparticles were investigated using small-angle X-ray scattering and rheology. The results provide effective strategies for formulating highly efficient pollutant-removal systems using nanotechnology.

Summary: The efficacy of drugs is often challenged by issues such as premature degradation, low solubility, side effects, and rapid clearance from the circulatory system. Surfactants play a pivotal role in solubilizing a wide variety of drug molecules through micellization in physiologically relevant fluids. They offer advantages over conventional liposomes and phospholipid-based formulations, including higher micellar stability, ease of formation, and lower maintenance expenses. This review critically analyzes the interactions between loaded drugs and surfactants in micellar delivery systems, highlighting the need for a better understanding of these interactions.

Summary: The critical micellar concentration (cmc) is a fundamental property of surfactant solutions, which can be determined using a concentration model and equations for different surfactant properties. This modular concept allows for systematic and unambiguous determination of cmc, and can be applied to study both surfactants as well as non-surfactant systems.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
