Giant vesicles in electric fields [PDF]
Soft Matter, 2007 This review is dedicated to electric field effects on giant unilamellar vesicles, a cell-size membrane system. We summarize various types of behavior observed when vesicles are subjected either to weak AC fields at various frequency, or to strong DC pulses.

Dynamic monitoring of a bi-enzymatic reaction at a single biomimetic giant vesicle.
In Analysis, 2020 Giant unilamellar vesicles were used as individual biomimetic micro-reactors wherein a model bi-enzymatic reaction involving a glucose oxidase (GOx) and horseradish peroxidase (HRP) was monitored by confocal microscopy.

Evolution of Proliferative Model Protocells Highly Responsive to the Environment
Life, 2022 In this review, we discuss various methods of reproducing life dynamics using a constructive approach. An increase in the structural complexity of a model protocell is accompanied by an increase in the stage of reproduction of a compartment (giant ...

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 ...

A simple method to make, trap and deform a vesicle in a gel
Scientific Reports, 2023 We present a simple method to produce giant lipid pseudo-vesicles (vesicles with an oily cap on the top), trapped in an agarose gel. The method can be implemented using only a regular micropipette and relies on the formation of a water/oil/water double ...

Formation of Oligovesicular Vesicles by Micromanipulation
Membranes, 2011 Cell-sized lipid bilayer membrane vesicles (giant vesicles, GVs) or semi-vesicles were formed from egg yolk phosphatidylcholine on a platinum electrode under applied electric voltage by electroformation.
