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.

Mechanistic Study of Membrane Disruption by Antimicrobial Methacrylate Random Copolymers by the Single Giant Vesicle Method.

Langmuir, 2021
Cationic amphiphilic polymers have been a platform to create new antimicrobial materials that act by disrupting bacterial cell membranes. While activity characterization and chemical optimization have been done in numerous studies, there remains a gap in

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,

Electroformation of giant unilamellar vesicles in saline solution

Colloids and Surfaces B: Biointerfaces, 2016
Giant unilamellar vesicle (GUV) formation on indium tin oxide (ITO) electrodes in saline solution and from charged lipids has proven to be difficult in the past. Yet the best cell membrane models contain charged lipids and require physiological conditions. We present a way to overcome this problem by using plasma cleaned ITO electrodes.

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),

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.

Deformation dynamics of giant unilamellar vesicles in the large surface-to-volume ratio regime: the emergence of neuron-like morphology.

Langmuir, 2020
Deformation of liposomes, or lipid vesicles, has been investigated extensively in terms of the thermodynamic equilibrium of the bending energy of the lipid bilayer membrane.

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.
