Characterisation of mixed micelles
been characterized quite well using a variety of techniques individually and in combination over the last decade. Interest in these surfactant systems stems from a broad application base. These surfactant systems, or “detergents” have found application in oil recovery due to enhanced solubility, higher cloud points, and lower Krafft points than the corresponding pure surfactant in solution. The...
متن کاملGrowth of Mixed Nonionic Micelles
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...
متن کاملStructure of the integrin beta3 transmembrane segment in phospholipid bicelles and detergent micelles.
Integrin adhesion receptors transduce bidirectional signals across the plasma membrane, with the integrin transmembrane domains acting as conduits in this process. Here, we report the first high-resolution structure of an integrin transmembrane domain. To assess the influence of the membrane model system, structure determinations of the beta3 integrin transmembrane segment and flanking sequence...
متن کاملLow Molecular Weight Micelles
I.F. Uchegbu et al. (eds.), Fundamentals of Pharmaceutical Nanoscience, DOI 10.1007/978-1-4614-9164-4_2, © Springer Science+Business Media New York 2013 Abstract Low molecular weight amphiphile micelles are formed from the selfassembly of comparatively hydrophilic amphiphiles (molecular weight <1,500 Da). These structures may be spherical or present as nanofi bres in the case of peptide amphiph...
متن کاملBrownian dynamics of mixed surfactant micelles.
We investigate micelle formation in a system containing two or more different amphiphiles with different geometries using a stochastic molecular-dynamics (MD) simulation method. For a binary system containing two amphiphiles, we calculate the critical micelle concentration (CMC) and cluster distribution for the mixture at several mole fractions and compare the simulation results with those pred...
