Micellization of cationic Gemini surfactants with various counterions and their interaction with DNA in aqueous solution

The micellization of six cationic Gemini surfactants with various counterions and their interaction with DNA in aqueous solution is examined by isotheral titration microcalorimetry and conductivity measurements. The conclusion states that the interactions of all the surfactants with DNA is dependent on the DNA concentration and may be associated with each micelle interacting with more than one DNA molecule.
