pH Sensing by Lipids in Membranes: The Fundamentals of pH-driven Migration, Polarization and Deformations of Lipid Bilayer Assemblies
Miglena I. Angelova, Anne-Florence Bitbol, Michel Seigneuret +6
Most biological molecules contain acido-basic groups that modulate their structure and interactions. A consequence is that pH gradients, local heterogeneities and dynamic variation…
Interplay of packing and flip-flop in local bilayer deformation. How phosphatidylglycerol could rescue mitochondrial function in a cardiolipin-deficient yeast mutant
Nada Khalifat, Mohammad Rahimi, Anne-Florence Bitbol +5
In a previous work, we have shown that a spatially localized transmembrane pH gradient, produced by acid micro-injection near the external side of cardiolipin-containing giant unil…
Lipid membrane deformation in response to a local pH modification: theory and experiments
Anne-Florence Bitbol, Nicolas Puff, Yuka Sakuma +3
We study the deformation of a lipid membrane in response to a local pH modification. Experimentally, a basic solution is microinjected close to a giant unilamellar vesicle. A local…
Dynamical membrane curvature instability controlled by intermonolayer friction
Anne-Florence Bitbol, Jean-Baptiste Fournier, Miglena I. Angelova +1
We study a dynamical curvature instability caused by a local chemical modification of a phospholipid membrane. In our experiments, a basic solution is microinjected close to a gian…
Stick-slip instability for viscous fingering in a gel
N. Puff, G. Debregeas, J. -M. di Meglio +3
The growth dynamics of an air finger injected in a visco-elastic gel (a PVA/borax aqueous solution) is studied in a linear Hele-Shaw cell. Besides the standard Saffmann-Taylor inst…
