Simulation of biological vesicles using a phase-field approach — •Thomas Nevolianis1, Erik Wittemeier1, and Dmitry Chigrin2 — 1Dept. of Physics, RWTH Aachen University, Otto-Blumenthal-Strasse 18, 52074 Aachen, Germany — 2DWI - Leibniz Institute for Interactive Materials, Forckenbeckstrasse 50, 52074 Aachen, Germany
The understanding of shape transformations and dynamic behavior of biomembrane vesicles is of fundamental importance in biological and physical sciences. In this study, the three-dimensional deformations of biological vesicles with prescribed volume and surface area, are numerically investigated using a phase-field approach. Interactions of a vesicle with other vesicles, substrate, and fluid flow are incorporated into the theoretical and numerical model. The developed phase-field model is applied to systematically study constraint and unconstraint shape evolution of growing prebiotic vesicles.
