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.

Self‐Assembly of Giant Unilamellar Vesicles by Film Hydration Methodologies

Advanced Biosystems, 2019
Self‐assembly of lipids or polymeric amphiphiles into vesicular structures has been achieved by various methods since the first generation of liposomes in the 1960s.

Elucidating the Membrane Dynamics and Encapsulation Mechanism of Large DNA Molecules Under Molecular Crowding Condition Using Giant Unilamellar Vesicles.

ACS Synthetic Biology, 2020
The conservation throughout evolution of membrane-bound structures that encapsulate genomic material indicates the exist-ence of a simple, physical mechanism that facilitates the enclosing of long-strand DNA by lipid bilayers.

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),

Giant Unilamellar Vesicle Microarrays for Cell Function Study

Analytical Chemistry, 2018
Giant unilamellar vesicles (GUVs) are widely used as artificial cell models which contribute to elucidate fundamental questions on origin of life and cell functions. Herein, the GUV microarrays were developed using a point-to-plane electrode system combined with microcontact stripping technique.

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.

Electroformation of Giant Unilamellar Vesicles: Investigating Vesicle Fusion versus Bulge Merging

Langmuir, 2016
Partially ordered stacks of phospholipid bilayers on a flat substrate can be obtained by the evaporation of a spread droplet of phospholipid-in-chloroform solution. When exposed to an aqueous buffer, numerous micrometric buds populate the bilayers, grow in size over minutes, and eventually detach, forming the so-called liposomes or vesicles.

Interaction of Giant Unilamellar Vesicles with the Surface Nanostructures on Dragonfly Wings.

Langmuir, 2019
The waxy epicuticle of dragonfly wings contains a unique nanostructured pattern that exhibits bactericidal properties. In light of emerging concerns of antibiotic resistance, these mechano-bactericidal surfaces represent a particularly novel solution by ...
