Birthing of a daughter vesicle in a model system for self-reproduction vesicles
Petch Khunpetch, Yuka Sakuma, Masayuki Imai +1
Sakuma and Imai [Phys. Rev. Lett. 107, 198101 (2011)] established a temperature-controlled cyclic process for a model system of self-reproducing vesicles without feeding. The vesic…
Hydrodynamic synchronization and collective dynamics of colloidal particles driven along a circular path
Takumi Miyamoto, Masayuki Imai, Nariya Uchida
We study theoretically the collective dynamics of particles driven by an optical vortex along a circular path. Phase equations of N particles are derived by taking into account bot…
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…
Shape transformations of toroidal vesicles
Hiroshi Noguchi, Ai Sakashita, Masayuki Imai
Morphologies of genus-1 and 2 toroidal vesicles are studied numerically by dynamically triangulated membrane models and experimentally by confocal laser microscopy. Our simulation…
Confinement-induced shape transitions in multilamellar vesicles
Ai Sakashita, Masayuki Imai, Hiroshi Noguchi
Morphologies of a vesicle confined in a spherical vesicle were explored experimentally by fast confocal laser microscopy and numerically by a dynamically-triangulated membrane mode…
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…
