Abstract: The use of electric fields as an external stimulus has been shown to be an effective technique for engineering vesicle behavior in a wide range of biotechnological applications. Electroporation has been successfully utilized for introducing genes or drugs into cells and cancer treatments. As a powerful cell manipulation method, electric fields have been used in tissue ablation, wound healing, and electroformation and electrofusion of giant vesicles. These important applications have motivated theoretical and computational studies on electrohydrodynamics of vesicles in order to gain a better understanding of the variety of membrane responses under the influence of electric and flow fields. In this talk, the work devoted to developing a robust computational framework using isogeometric analysis and the phase-field method to model the morphological evolution of single- and multi-phase biomembranes will be presented. We developed a three-dimensional isogeometric analysis formulation for the phase-field constrained optimization problem of morphological evolution of vesicles in electrical fields. The effect of the flexoelectricity and the conductivity ratio of the electrolyte on vesicle equilibrium shape were studied through several 3D numerical examples. We captured sphere-oblate and sphere-prolate shape transitions under varying conductivity ratio.
