Laser Tweezer Deformation of Giant Unilamellar Vesicles

2007
Two methods are presented for deforming giant unilamellar vesicles with holographic optical tweezers. The first allows ultrahigh spatial- and temporal-resolution optical tracking of membrane deformations, by using embedded silica microspheres in a giant unilamellar vesicle as tracers.

Electrostatic interaction effects on the size distribution of self-assembled giant unilamellar vesicles.

Physical Review E, 2020
The influence of electrostatic conditions (salt concentration of the solution and vesicle surface charge density) on the size distribution of self-assembled giant unilamellar vesicles (GUVs) is considered.

Interfacial Phases on Giant Unilamellar Vesicles

ASME 2012 Summer Bioengineering Conference, Parts A and B, 2012
Lipid nanodomains in cell membranes are believed to play a significant role in a number of critical cellular processes (Elson, et al., 2010). These include, for example, replication processes in enveloped viruses such as bird flu and HIV and signaling mechanisms underlying pathological conditions such as cancer.

Deformation of giant unilamellar vesicles under osmotic stress

Colloids and Surfaces B: Biointerfaces, 2018
Biological membrane plays an important role in maintaining an osmotic equilibrium between the cytoplasm and the extracellular solution of cells. Here, the giant unilamellar vesicles (GUVs) as cell models were used to investigate the effect of osmotic stress on phospholipid membranes. The deformation of GUVs, including inward budding and outward budding,

Deformation Modes of Giant Unilamellar Vesicles Encapsulating Biopolymers

ACS Synthetic Biology, 2018
The shapes of giant unilamellar vesicles (GUVs) enclosing polymer molecules at relatively high concentration, used as a model cytoplasm, significantly differ from those containing only small molecules. Here, we investigated the effects of the molecular weights and concentrations of polymers such as polyethylene glycol (PEG), bovine serum albumin (BSA),

Clustering of Giant Unilamellar Vesicles (GUVs) Promoted by Covalent and Non-Covalent Bonding of Functional Groups at Membrane-Embedded Peptides.

Bioconjugate chemistry, 2019
Access to clusters of cell-sized globular objects such as giant unilamellar vesicles (GUVs) is of increasing interest due to their potential applications in prototissue and cell-cell adhesion studies.

Magnetically Controlled Polymer Giant Unilamellar Vesicles

Small
AbstractGiant unilamellar vesicles (GUVs) are essential tools for mimicking cellular processes such as membrane transport and for applications including sensing or protocell development. While it is often desirable to immobilize GUVs in these contexts, many immobilization approaches are irreversible, or limited in flexibility and scalability.

Volume transition in composite poly(NIPAM)–giant unilamellar vesicles

Soft Matter, 2008
We have recently reported on the formation of composite gel vesicles prepared by the photopolymerization and crosslinking of poly(N-isopropyl-acrylamide) [poly(NIPAM)] inside phospholipid giant unilamellar vesicles (GUVs). Here we present a detailed study of the thermo-responsive behaviour of such composite vesicles.

Reconstitution and Anchoring of Cytoskeleton inside Giant Unilamellar Vesicles

ChemBioChem, 2008
AbstractAmong the requirements for all life forms is the ability to self‐replicate. In eukaryotic cellular systems, this division is achieved through cytokinesis, and is facilitated by the (re)arrangement and interaction of cytoskeletal proteins with lipids and other proteins localized to the plasma membrane. A fascinating challenge of modern synthetic
