Abstract
English abstract
The purpose of this project is to examine the effects of alcohol on the lysis tension of DMPC vesicles. By extruding multilamellar vesicles, we obtain a monodisperse solution of unilamellar vesicles. By varying the amount of alcohol in the membrane we expect a change in the lysis tension. A model of the extrusion process suggest that this change in lysis tension will affect the size of the extruded vesicles. We measure the hydrodynamic radius of the vesicles by dynamic light scattering. Our results are inconclusive and we suspect systematik errors in the experiment. We are not able to draw conclusion about the proposed model. Based on difficulties in the experiment, we discuss sources of errors and uncertainties, in an attempt to pass on our experiences with dynamic light scattering experiments.
