Critical micelle concentrations of lipoteichoic acids [PDF]
Purified lipoteichoic acids (LTAs) from several gram-positive organisms have been shown, by methods involving spectral changes of an added merocyanine dye probe, to have critical micelle concentrations in the range of 1 to 10 micrograms/ml, suggesting that acylated LTAs in their monomer forms may represent the major configuration of extracellular LTAs ...

Critical Micelle Concentrations in Surfactant Mixtures and Blends by Simulation [PDF]
We explore the use of coarse-grained dissipative particle dynamics simulations to predict critical micelle concentrations (CMCs) in polydisperse surfactant mixtures and blends. By fitting pseudo-phase separation models (PSMs) to aqueous solutions of binary surfactant mixtures at selected compositions above the CMC, we avoid the need for expensive ...
