Influence of shear flow on vesicles near a wall: a numerical study
Sreejith Sukumaran, Udo Seifert
We describe the dynamics of three-dimensional fluid vesicles in steady shear flow in the vicinity of a wall. This is analyzed numerically at low Reynolds numbers using a boundary e…
Rupture of multiple parallel molecular bonds under dynamic loading
Udo Seifert
Biological adhesion often involves several pairs of specific receptor-ligand molecules. Using rate equations, we study theoretically the rupture of such multiple parallel bonds und…
Mapping vesicle shapes into the phase diagram: A comparison of experiment and theory
H. -G. Döbereiner, E. Evans, M. Kraus +2
Phase-contrast microscopy is used to monitor the shapes of micron-scale fluid-phase phospholipid-bilayer vesicles in aqueous solution. At fixed temperature, each vesicle undergoes…
Straightening of Thermal Fluctuations in Semi-Flexible Polymers by Applied Tension
Udo Seifert, Wolfgang Wintz, Philip Nelson
We investigate the propagation of a suddenly applied tension along a thermally excited semi-flexible polymer using analytical approximations, scaling arguments and numerical simula…
The Role of Bilayer Tilt Difference in Equilibrium Membrane Shapes
Udo Seifert, Julian Shillcock, Philip Nelson
Lipid bilayer membranes below their main transition have two tilt order parameters, corresponding to the two monolayers. These two tilts may be strongly coupled to membrane shape b…
Giant vesicles at the prolate-oblate transition: A macroscopic bistable system
H. -G. Doebereiner, U. Seifert
Giant phospholipid vesicles are shown to exhibit thermally activated transitions between a prolate and an oblate shape on a time scale of several seconds. From the fluctuating cont…
