Self-assembly of liquid crystal block copolymer PEG-b-smectic polymer in pure state and in dilute aqueous solution
B. Xu, R. Pinol, M. Nono-Djamen +5
A series of amphiphilic LC block copolymers, in which the hydrophobic block is a smectic polymer poly(4-methoxyphenyl 4-(6-acryloyloxy-hexyloxy)-benzoate) (PA6ester1) and the hydro…
Smectic Polymer Vesicles
Lin Jia, Amin Cao, Daniel Levy +5
Polymer vesicles are stable robust vesicles made from block copolymer amphiphiles. Recent progress in the chemical design of block copolymers opens up the exciting possibility of c…
Membrane buckling induced by curved filaments
Martin Lenz, Daniel J. G. Crow, Jean-François Joanny
We present a novel buckling instability relevant to membrane budding in eukaryotic cells. In this mechanism, curved filaments bind to a lipid bilayer without changing its intrinsic…
Coherent motion of stereocilia assures the concerted gating of hair-cell transduction channels
Andrei S. Kozlov, Thomas Risler, A. J. Hudspeth
The hair cell's mechanoreceptive organelle, the hair bundle, is highly sensitive because its transduction channels open over a very narrow range of displacements. The synchronous g…
Pushing off the walls: a mechanism of cell motility in confinement
R. J. Hawkins, M. Piel, G. Faure-Andre +4
We propose a novel mechanism of cell motility, which relies on the coupling of actin polymerization at the cell membrane to geometric confinement. We consider a polymerizing viscoe…
