Static and quasielastic light-scattering measurements were utilized to investigate the shape, size, and polydispersity of mixed micelles composed of the nonionic surfactants dodecyl hexaoxyethylene glycol monoether (C12E6) and dodecyl octaoxyethylene glycol monoether (C12E8) in aqueous solutions. We determined the molecular weight and diffusion coefficient of these micelles and showed that they...

Rigorous theory for gradient diffusion in hard-sphere suspensions is adapted to locally monodisperse, nonionic micellar solutions with solute, and effectively used predict ternary matrices [D] acquired using the Taylor dispersion method.

i-i E1IE HAVE BEEN a number of reports iii the literature regarding the use of surface active agents in zone electrophoretic studies of 1)100(1 serum proteins and hpoprotems. Ardr (1) found that cationic detergents formed, with serum protenis, complexes that migrated like $-lipoproteins, while aiiionic detergents formed complexes that clectrophoretically resembled -1ipoproteins. More recently, ...

In this work, a novel protocol was developed for size tuning and cetyltrimethylammonium bromide (CTAB) removal of gold nanorods using commercially available nonionic fluorosurfactants (FSN), an excellent candidate for PEG and other modification reagents. The tunable gold nanorods can easily be obtained by stopping the ligand replacement reaction at different time intervals. The FSN-coated gold ...

The apoprotein of human serum beta lipoprotein has been prepared in a lipid-free and soluble form by a technique of interfacial extraction in the presence of guanidinium hydrochloride and nonionic amphiphile. Gel permeation chromatography of maleylated apobeta lipoprotein separates two protein fractions with different amino acid compositions. The smaller particle has a molecular weight of 2.6 x...
