Using small molecules to facilitate exchange of bicarbonate and chloride anions across liposomal membranes [PDF]
, 2009 Bicarbonate is involved in a wide range of biological processes, which include respiration, regulation of intracellular pH and fertilization. In this study we use a combination of NMR spectroscopy and ion-selective electrode techniques to show that the ...

A Note on Vestigial Osmotic Pressure
Membranes, 2023 Recent experiments have indicated that at least a part of the osmotic pressure across the giant unilamellar vesicle (GUV) membrane was balanced by the rapid formation of the monodisperse daughter vesicles inside the GUVs through an endocytosis-like ...

Pulling Membrane Nanotubes from Giant Unilamellar Vesicles [PDF]
Journal of Visualized Experiments, 2017 The reshaping of the cell membrane is an integral part of many cellular phenomena, such as endocytosis, trafficking, the formation of filopodia, etc. Many different proteins associate with curved membranes because of their ability to sense or induce membrane curvature.

Membrane sculpting by curved DNA origami scaffolds
Nature Communications, 2018 BAR domain proteins feature a “banana-like” shape which is thought to aid membrane scaffolding and membrane tubulation. Here authors use DNA origami mimicking BAR domains, giant unilamellar vesicles and fluorescence imaging to study how different BAR ...

Asymmetric Oxidation of Giant Vesicles triggers Curvature-associated Shape Transition and Permeabilization. Running title: Oxidation of Vesicles produces Curvature [PDF]
Biophysical Journal, Biophysical Society, 2009, 97 (11),
pp.2904-2912, 2019 (200 words) Oxidation of unsaturated lipids is a fundamental process involved in cell bioenergetics as well as in cell death. Using giant unilamellar vesicles and a chlorin photosensitizer, we asymmetrically oxidized the outer or inner monolayers of lipid membranes.

Heat-induced formation of single giant unilamellar vesicles [PDF]
, 2011 Giant unilamellar vesicles (GUVs) are an excellent model system for the investigation of lipid membranes, the study of membrane proteins and ion channels in a biomimetic environment, and in the creation of artificial cells.

The Influence of high pressure on the bending rigidity of model membranes [PDF]
, 2015 Curvature is a fundamental lipid membrane property that influences many membrane-mediated biological processes and dynamic soft materials. One of the key parameters that determines the energetics of curvature change is the membrane bending rigidity ...

Entry of Microparticles into Giant Lipid Vesicles by Optical Tweezers [PDF]
, 2023 Entry of micro- or nano-sized objects into cells or vesicles made of lipid membranes occur in many processes such as entry of viruses in host cells, microplastics pollution, drug delivery or biomedical imaging. Here, we investigated the microparticle crossing of lipid membranes in giant unilamellar vesicles in the absence of strong binding interactions
