“…Due to model shortcomings, C * values are expected to be method dependent. Nevertheless, they were found to fall within the range of C * data reported in the literature. − Within the framework of our method, the precision of the determined values of C * was found to be ≈3% and ≈0.01 g·L –1 represents the lowest value of C * that can be detected by Rayleigh interferometry based on Brij-30 results. While Rayleigh interferometry was employed for the characterization of C ( Y ) in our experiments, concentration profiles can also be extracted using other techniques such as absorption spectroscopy.…”

“…In the present work, we use precision Rayleigh interferometry, which gives the one-dimensional refractive-index profile inside a vertical channel in which a surfactant solution is interfaced with its solvent. , We determine C * for three well-known surfactants in water at 25 °C. These surfactants are Triton X-100 (TX-100), as an example of nonionic surfactant ( C * = 0.23–0.24 mM, ≈0.15 g·L –1 ), − sodium dodecyl sulfate (SDS), as an example of ionic surfactant ( C * = 7.6–8.4 mM, ≈2.3 g·L –1 ), ,, and poly(oxyethylene)(4)Lauryl Ether (Brij-30) to examine method sensitivity as this nonionic surfactant has a significantly low C * value (0.039–0.085 mM, ≈0.02 g·L –1 ). ,, An important problem in the field of surfactants is to examine the effect of additives on physicochemical properties such as micellization and cloud point . In our case, we characterized the dependence of C * on salt type and concentration in the case of TX-100 to examine method precision.…”

Micellization is a phenomenon of central importance in surfactant solutions. Here, we demonstrate that the diffusion-based spreading of the free boundary between a micellar aqueous solution and pure water yields a one-dimensional spatial profile of surfactant concentration that can be used to identify the critical micelle concentration, here denoted as C*. This can be achieved because dilution of micelles into water leads to their dissociation at a well-defined position along the concentration profile and an abrupt increase in the diffusion coefficient. Rayleigh interferometry was successfully employed to determine C* values for three well-known surfactants in water at 25 °C: Triton X-100 (TX-100), sodium dodecyl sulfate (SDS), and poly(oxyethylene)(4)Lauryl Ether (Brij-30). The dependence of C* on salt concentration was also characterized for TX-100 in the presence of Na2SO4, NaCl, and NaSCN. Accurate values of C* can be directly identified by visual inspection of the corresponding concentration-gradient profiles. To apply the method of least squares to experimental concentration profiles, a mathematical expression was derived from Fick’s law and the pseudophase separation model of micellization with the inclusion of appropriate modifications. While Rayleigh interferometry was employed in our experiments, this approach can be extended to any experimental technique that yields one-dimensional profiles of surfactant concentration. Moreover, diffusion-driven surfactant disaggregation is precise, noninvasive, requires single-sample preparation, and applies to both nonionic and ionic surfactants. Thus, this work provides the foundation of diffusion-driven dilution methods, thereby representing a valuable addition to existing techniques for the determination of C*.

“…The average interaction parameter values show that TRX generates stronger sinergistic interactions with investigated bile salts than SLES. Many recent studies have confirmed that synergistic effect generally occurs in anionic-nonionic surfactant mixtures, improving stability of the system [ 41 - 48 ]. In previously investigated sodium deoxycholate-Triton X-100 binary system, synergistic interaction is reported, with β av = -0.9 [ 28 ].…”

BackgroundIn order to develop colloidal drug carriers with desired properties, it is important to determine physico-chemical characteristics of these systems. Bile salt mixed micelles are extensively studied as novel drug delivery systems. The objective of the present investigation is to develop and characterize mixed micelles of nonionic (Triton X-100) or anionic (sodium lauryl ether sulfate) surfactant having oxyethylene groups in the polar head and following bile salts: cholate, deoxycholate and 7-oxodeoxycholate.ResultsThe micellization behaviour of binary anionic-nonionic and anionic-anionic surfactant mixtures was investigated by conductivity and surface tension measurements. The results of the study have been analyzed using Clint's, Rubingh's, and Motomura's theories for mixed binary systems. The negative values of the interaction parameter indicate synergism between micelle building units. It was noticed that Triton X-100 and sodium lauryl ether sulfate generate the weakest synergistic interactions with sodium deoxycholate, while 7-oxodeoxycholate creates the strongest attractive interaction with investigated co-surfactants.ConclusionIt was concluded that increased synergistic interactions can be attributed to the larger number of hydrophilic groups at α side of the bile salts. Additionally, 7-oxo group of 7-oxodeoxycholate enhance attractive interactions with selected co-surfactants more than 7-hydroxyl group of sodium cholate.

“…The decellularization was performed using a modification of the protocol from Ott et al 36 We combined sodium dodecyl sulfate (SDS) and Triton X100, thereby lowering both the effective concentration and critical micellar concentration of the combined detergents 37 . The advantage of this strategy is the improvement in decellularization and prevention of tissue‐collapse 38 while the retention of detergents is reduced 39 …”

Spatiotemporal Extracellular Matrix Modeling for in Situ Cell Niche Studies

Extracellular matrix (ECM) components govern a range of cell functions, such as migration, proliferation, maintenance of stemness, and differentiation. Cell niches that harbor stem-/progenitor cells, with matching ECM, have been shown in a range of organs, although their presence in the heart is still under debate. Determining niches depends on a range of in vitro and in vivo models and techniques, where animal models are powerful tools for studying cell-ECM dynamics; however, they are costly and time-consuming to use. In vitro models based on recombinant ECM proteins lack the complexity of the in vivo ECM. To address these issues, we present the spatiotemporal extracellular matrix model for studies of cell-ECM dynamics, such as cell niches. This model combines gentle decellularization and sectioning of cardiac tissue, allowing retention of a complex ECM, with recellularization and subsequent image processing using image stitching, segmentation, automatic binning, and generation of cluster maps. We have thereby developed an in situ representation of the cardiac ECM that is useful for assessment of repopulation dynamics and to study the effect of local ECM composition on phenotype preservation of reseeded mesenchymal progenitor cells. This model provides a platform for studies of organ-specific cell-ECM dynamics and identification of potential cell niches.
