摘要

The micellization of six cationic gemini surfactants with various counterions,[C12H25 (CH3) 2N (CH2) 6N (CH3) 2C12H25] X2, designated as C12C6C12X2, with X= F-, Cl-, Br-, Ac-, NO3-, and 1/2SO42-in aqueous solutions has been investigated by isothermal titration microcalorimetry (ITC) and conductivity measurements. The interaction of these surfactants with DNA in aqueous solutions has also been investigated by isothermal titration ...
