In this work, the interaction between sodium cholate (NaC) aggregates and quercetin has been studied in pH 7.4 sodium phosphate buffer. Surface tension measurement reveals that the presence of quercetin leads NaC to have increased critical aggregation concentrations, owing to the electrostatic repulsion between negative charged NaC and anionic quercetin species. As NaC monomers gradually aggregate...
The absorption and fluorescence measurements have been used to study the interactions between cationic gemini surfactant micelles of alkanediyl-α,ω-bis(dodecyldimethylammonium bromide) (C 12 C s C 12 Br 2 , where s=2, 3, 4, 6, and 12, indicating the number of carbons in the spacer) with trianionic curcumin (Cur 3− ) at pH 13. With increasing spacer length of...
