Osmotic Gradients Induce Bio-reminiscent Morphological Transformations in Giant Unilamellar Vesicles
Frontiers in Physiology, 2012 We report observations of large-scale, in-plane and out-of-plane membrane deformations in giant uni- and multilamellar vesicles composed of binary and ternary lipid mixtures in the presence of net transvesicular osmotic gradients.

Polyelectrolyte-induced peeling of charged multilamellar vesicles
, 2005 We study mixtures of charged surfactants, which alone in solution form uni- and multilamellar vesicles, and oppositely charged polyelectrolytes (PEs).

Induced phagocytic particle uptake into a giant unilamellar vesicle
Soft Matter, 2014 Phagocytosis, the uptake and ingestion of solid particles into living cells, is a central mechanism of our immune system. Due to the complexity of the uptake mechanism, the different forces involved in this process are only partly understood. Therefore the usage of a giant unilamellar vesicle (GUV) as the simplest biomimetic model for a cell allows one

Mixed lipid bilayers with locally varying spontaneous curvature and bending
, 2014 A model of lipid bilayers made of a mixture of two lipids with different average compositions on both leaflets, is developed. A Landau hamiltonian describing the lipid-lipid interactions on each leaflet, with two lipidic fields $\psi_1$ and $\psi_2$, is ...

Membrane Protrusion Coarsening and Nanotubulation within Giant Unilamellar Vesicles
Journal of the American Chemical Society, 2011 Hydrophobic side groups on a stimuli-responsive polymer, encapsulated within a single giant unilamellar vesicle, enable membrane attachment during compartment formation at elevated temperatures. We thermally modulated the vesicle through implementation of an IR laser via an optical fiber, enabling localized directed heating.

Vesicle dynamics in elongation flow: Wrinkling instability and bud formation
, 2007 We present experimental results on the relaxation dynamics of vesicles subjected to a time-dependent elongation flow. We observed and characterized a new instability, which results in the formation of higher order modes of the vesicle shape (wrinkles ...
