Micelle Size and Shape. Polydispersity

The methods mentioned above do not measure the micellar aggregation number itself but rather some micellar size. A direct determination of aggregation numbers can be performed by analysing some physico-chemical parameter in terms of the equilibria involved equilibrium analyses on the basis of potentiometric data have been pioneered by Danielsson and co-workers who studied short-chain, not typically micelle-forming, amphiphiles in the presence of added electrolyte (see above). 

For hexadecyltrimethylammonium bromide (CTAB) there is evidence of several types (X-ray diffraction83, conductance anisotropy192, flow birefringence193,

Detailed studies of micellar size and shape using quasi-elastic light scattering have recently been presented for sodium dodecylsulfate33. To reduce the influence
