Summary on Grant Application Form |

The main aim of the project is to establish a quantitative theoretical model which describes the mechanism and kinetics of the micelle-to-vesicle transition. This model will then be tested using recent detailed experimental investigations as well as new, mainly light scattering experiments which will be performed during the course of this project in response to predictions from the model. We will concentrate on two experimental systems; lecithin-bile salt mixtures and cationic-anionic ('catanionic') surfactants, which are believed to form 'kinetically trapped' and equilibrium vesicles, respectively. The theoretical model will consider four steps: fast formation of small intermediate disc-like micelles from initially spherical or worm-like micelles; coalescence or 'ripening' of these discs into larger disc-like bilayer intermediates; closure of the enlarged discs to form unilamellar vesicles; coarsening of these vesicles by a slow coalescence or ripening mechanism.
