Effect of an electric field on a floating lipid bilayer: a neutron reflectivity study
arXiv:cond-mat/0611162 · doi:10.1140/epje/i2006-10054-8
Abstract
We present here a neutron reflectivity study of the influence of an alternative electric field on a supported phospholipid double bilayer. We report for the first time a reproducible increase of the fluctuation amplitude leading to the complete unbinding of the floating bilayer. Results are in good agreement with a semi-quantitative interpretation in terms of negative electrostatic surface tension.
