Hierarchical unilamellar vesicles of controlled compositional heterogeneity. [PDF]
PLoS ONE, 2012 Eukaryotic life contains hierarchical vesicular architectures (i.e. organelles) that are crucial for material production and trafficking, information storage and access, as well as energy production. In order to perform specific tasks, these compartments

Asymmetric Giant Unilamellar Vesicles [PDF]
Biophysical Journal, 2010 The lipid composition of the eukaryotic plasma membrane is asymmetric; that is, if the bilayer is considered to consist of two leaflets, the outer-facing leaflet contains different lipids at different concentrations than the inner-facing leaflet. While there has been much speculation as to the physiological purpose of this asymmetry, it has been ...

Optimized cDICE for Efficient Reconstitution of Biological Systems in Giant Unilamellar Vesicles
bioRxiv, 2021 Giant unilamellar vesicles (GUVs) are often used to mimic biological membranes in reconstitution experiments. They are also widely used in research on synthetic cells as they provide a mechanically responsive reaction compartment that allows for ...

Gel-Assisted Formation of Giant Unilamellar Vesicles [PDF]
Biophysical Journal, 2013 Giant unilamellar vesicles or GUVs are systems of choice as biomimetic models of cellular membranes. Although a variety of procedures exist for making single walled vesicles of tens of microns in size, the range of lipid compositions that can be used to grow GUVs by the conventional methods is quite limited, and many of the available methods involve ...

Chemical communication at the synthetic cell/living cell interface
Communications Chemistry, 2021 Synthetic models of cells are becoming increasingly sophisticated, but engineering communication between these and living cells remains challenging. Here the authors review modes of communication and signal processing between living cells and synthetic ...

Shear stress induced lipid order and permeability changes of giant unilamellar vesicles.
Biochimica et Biophysica Acta - General Subjects, 2022 BACKGROUND The permeability of a lipid bilayer is a function of its phase state and depends non-linearly on thermodynamic variables such as temperature, pressure or pH.

Block Copolymer Giant Unilamellar Vesicles for High-Throughput Screening
CHIMIA, 2022 Bottom-up synthetic cells offer the potential to study cellular processes with reduced complexity. Giant unilamellar vesicles (GUVs) can mimic cells in their morphological characteristics because their architecture is precisely controllable.
