Abstract

We study theoretically phospholipid vesicle locomotion caused by adhesion. The problem is solved numerically, and an analytical solution is obtained in a perturbative scheme. The analytical result reproduces the numerical one. We provide an expression for the drift velocity as a function of relevant parameters when only local dissipation is present. We briefly discuss the transition from sliding to rolling when hydrodynamics are included. We mention situations where the vesicle may itself establish an adhesion gradient. We propose some simple experimental protocols.
