Micellization and adsorption characteristics of CHAPS

, 2000
The adsorption of CHAPS on hydrophobic latex particles was studied at 22 and 36 degrees C by determining the adsorbed amount and the enthalpy of adsorption. The adsorption process was compared to the micellization of the surfactant.

Three eras of micellization [PDF]

, 2002
Micellization is the precipitation of lipids from aqueous solution into aggregates with a broad distribution of aggregation number. Three eras of micellization are characterized in a simple kinetic model of Becker-Döring type.

Pathway Complexity Defines the Shape of Nucleic Acid‐Loaded Polyion Complex Micelles: Spheroids vs. Hexagonal Disks

Angewandte Chemie, EarlyView.
Same building blocks, different destinies. Pathway complexity directs nucleic acid–loaded polyion complex micelles along distinct assembly trajectories, resulting in either hexagonally shaped or spheroidal nanoparticles with distinct internal structuring.
