Biophysical Studies on the Interaction of Insulin with a Cationic Gemini Surfactant
A novel quaternary ammonium-based cationic gemini surfactant (S6) having 1,6 di-bromo hexane as a spacer, have been used and its interaction with insulin in aqueous solution (pH, 7.40) was investigated by several methods including fluorescence spectroscopy, UV-Vis spectroscopy, circular dichroism, dynamic light scattering, ζ-potential measurements, conductivity and transmission electron microsc...
متن کاملSpontaneous aggregate transition in mixtures of a cationic gemini surfactant with a double-chain cationic surfactant.
Controllable aggregate transitions were realized by mixing two kinds of cationic surfactants, hexylene-1,6-bis(dodecyldimethylammonium bromide) (C(12)C(6)C(12)Br(2)) and didodecyldimethylammonium bromide (DDAB). It was found that two parameters are the main factors determining the aggregation behavior of the mixed system, the total concentration of DDAB and C(12)C(6)C(12)Br(2) (C(T)), and the m...

متن کاملThermodynamic investigation of the interaction between anionic dye and cationic surfactant in aqueous solution
The interaction of anionic dye Acid Green 25 (AG) with cationic surfactant cetylpyridinium chloride (CPC) was studied by spectrophotometric method in 25oC and conductometric method in 25, 30, 35, 40 and 45oC. The specific conductance of dye – surfactant mixtures was measured. A decrease in measured specific conductance values of dyesurfactant mixture was caused by the formation of nonconducting...
متن کاملRemoval of Tetracycline Antibiotic from Aqueous Solution Using Zeolite-X Modified by Pyridium Bromide Cationic Surfactant: A Laboratory Study
Background and Objectives: Antibiotics are among the pollutants that have entered uncontrollably in the environment, and lead to serious environmental problems such as disrupting aquatic ecosystems, and causing health problems for humans and other organisms. Therefore, it is necessary to remove them from the environment. In the current study, zeolite modified by cationic surfactant of cetylpyr...
