Robot‐Assisted Measurement of the Critical Micelle Concentration

Advanced Intelligent Systems
The critical micelle concentration (CMC) is the key characterization of surfactants. To date, no method can yield sequential CMC measurements in an automated fashion.

Soil water solutes reduce the critical micelle concentration of quaternary ammonium compounds [PDF]

Environ Sci Pollut Res Int, 2020
Quaternary alkyl ammonium compounds (QAACs) are produced in large quantities for use as surfactants and disinfectants and also found in soils, sediments, and surface waters, where they are potentially involved in the selection of antibiotic resistance ...

A Source of Systematic Errors in the Determination of Critical Micelle Concentration and Micellization Enthalpy by Graphical Methods in Isothermal Titration Calorimetry [PDF]

Entropy, 2021
Isothermal titration calorimetry is frequently employed to determine the critical micelle concentration and the micellization enthalpy of surfactants in terms of geometrical characteristics of the titration curves.

Micelles with ultralow critical micelle concentration as carriers for drug delivery [PDF]

Nature Biomedical Engineering, 2018
Conventional micellar carriers disassemble into free surfactants when diluted at concentrations below the critical micelle concentration (CMC). This limits the bioavailability in vivo of injected hydrophobic drugs encapsulated in micellar systems.

The Critical Micelle Concentration of Cetomacrogol 1000

Journal of Pharmacy and Pharmacology, 1960
Abstract The critical micelle concentration of cetomacrogol has been determined by the iodine and solubilisation methods, and also from surface tension measurements. Results from the three methods were 0.0070, 0.006 to 0.008, and 0.0063 per cent respectively. The presence of sodium chloride in the solutions decreased the critical micelle

Measurement of Critical Micelle Concentration (CMC)

, 2021
The Critical Micelle Concentration (CMC) is the surfactant concentration above which the addition of a monomer leads to the formation of the first micelle. Above the CMC, monomers and micelles exist in dynamic equilibrium. Almost all physical properties of a surfactant solution exhibit a sharp concentration dependent discontinuity in the region of ...

α-Synuclein Forms Distinct Micelle-Like Assemblies at Low Ionic Strengths. [PDF]

Adv Sci (Weinh)
At high ionic strength, α‐synuclein forms diverse assemblies, including oligomers, fibrils, and condensates. Here, we show that at low ionic strength, α‐synuclein adopts a distinct, low‐abundance assembly state. These assemblies maintain a constant size above a critical concentration and do not coalesce, suggesting a micelle‐like organization ...
