Membrane Manipulation of Giant Unilamellar Polymer Vesicles with a Temperature‐Responsive Polymer

نویسندگان

چکیده

Understanding the complex behavior and dynamics of cellular membranes is integral to gain insight into division fusion processes. Bottom-up synthetic cells are as a platform for replicating probing behavior. Giant polymer vesicles more robust than liposomal counterparts, well having broad range chemical functionalities. However, stability membrane can prohibit dynamic processes such phase separation division. Here, we present method manipulating giant polymersomes using temperature responsive polymer. Upon elevation deformation was observed. cooling, relaxed became homogeneous again, with infrequent cells.

Spontaneous unilamellar polymer vesicles in aqueous solution.

A unilamellar polymeric vesicle is a self-assembled structure of a block copolymer that forms a spherical single bilayer structure with a hydrophobic interlayer and a hydrophilic surface. Due to their enhanced colloidal stability and mechanical property, controllable surface functionality, or tunable membrane thickness, polymeric vesicles are useful in nano and bio-science, providing potential ...

Asymmetric Hybrid Polymer–Lipid Giant Vesicles as Cell Membrane Mimics

Lipid membrane asymmetry plays an important role in cell function and activity, being for instance a relevant signal of its integrity. The development of artificial asymmetric membranes thus represents a key challenge. In this context, an emulsion-centrifugation method is developed to prepare giant vesicles with an asymmetric membrane composed of an inner monolayer of poly(butadiene)-b-poly(eth...

Quantitative Membrane Loading of Polymer Vesicles

We utilize a series of structurally homologous, multi-porphyrin-based, fluorophores (PBFs) in order to explore the capacity of polymer vesicles (polymersomes) to stably incorporate large hydrophobic molecules, non-covalently within their thick lamellar membranes. Through aqueous hydration of dry, uniform thin-films of amphiphilic polymer and PBF species deposited on Teflon, self-assembled polym...

Electroformation of Giant Vesicles on a Polymer Mesh

Electroformation of cell-sized lipid membrane vesicles (giant vesicles, GVs) from egg yolk phosphatidylcholine under applied electric voltage was examined on a substrate of a polymer mesh placed between two planar indium tin oxide coated glass electrodes. Under appropriate conditions, GVs were formed in good yield on meshes of various polymer materials, namely, hydrophobic poly(propylene), poly...

bSUM: A bead-supported unilamellar membrane system facilitating unidirectional insertion of membrane proteins into giant vesicles

Fused or giant vesicles, planar lipid bilayers, a droplet membrane system, and planar-supported membranes have been developed to incorporate membrane proteins for the electrical and biophysical analysis of such proteins or the bilayer properties. However, it remains difficult to incorporate membrane proteins, including ion channels, into reconstituted membrane systems that allow easy control of...
