Vesicles

The Nobel prize in Physiology/Medicine for 2013 was awarded to J. E. Rothman, R. W. Schekman and T C. Südhof for their work on vesicle traffic. Research on vesicles is not only key to our understanding of transport in cells, but also a promising route to drug delivery.

Vesicles in Nature and the Laboratory: Elucidation of Their Biological Properties and Synthesis of Increasingly Complex Synthetic Vesicles

Vesicles in Nature and the Laboratory: Elucidation of Their Biological Properties and Synthesis of Increasingly Complex Synthetic Vesicles

Inspiration–imitation–innovation: Parallel to the elucidation of the biological properties and physiological function of vesicles, increasingly elegant artificial vesicles are being reported. This Review provides an overview of the complex and rapidly developing fields of natural and synthetic vesicles and shows how the two fields can profit from one another.

Selective Electrochemical Bleaching of the Outer Leaflet of Fluorescently Labeled Giant Liposomes

Selective Electrochemical Bleaching of the Outer Leaflet of Fluorescently Labeled Giant Liposomes

Struck by lightning! Electrochemistry is a powerful tool to selectively bleach the fluorescence emitted by redox-active fluorophores localized on the outer leaflet of giant liposomes. This original fluorescence loss in electrobleaching (FLIE) procedure is reliable for exploring the phospholipid reorganization dynamics of a single leaflet in real time. This opens new perspectives to explore important biological and pharmacological issues.

Preparation of Monodisperse Hyper-Crosslinking Polymer Nanoparticles for Highly Efficient CO2 Adsorption

Preparation of Monodisperse Hyper‐Crosslinking Polymer Nanoparticles for Highly Efficient CO2 Adsorption

In this paper a combined method of vesicle bilayer templating and hyper-crosslinking to prepare monodisperse microporous polymer nanoparticles with a small size of 61 nm, a high Brunauere–Emmette–Teller surface area up to ≈1300 m2 g−1, and a very high micropore surface area above 1000 m2 g−1 is reported. It also shows the best CO2 uptake property among “Davankov Resins.”

Aqueous Self-Assembly of Y-Shaped Amphiphilic Block Copolymers into Giant Vesicles

Aqueous Self‐Assembly of Y‐Shaped Amphiphilic Block Copolymers into Giant Vesicles

A series of newly Y-shaped amphiphilic block polyurethane copolymers with two hydrophilic poly(ethylene oxide) (PEO) tails and one hydrophobic alkyl tail is synthesized, which can self-assemble into spherical micelles, small vesicles, and giant unilamellar vesicles by increasing the copolymer concentrations with a direct dissolution method in aqueous solution.

Self-Assembly of Bolaamphiphilic Molecules

Self‐Assembly of Bolaamphiphilic Molecules

The self-assembly of bolaamphiphilic molecules or bolas is receiving greater attention in recent times owing to their structural diversity and occurrence in natural Archaea species. Compared with the conventional single-headed amphiphiles, bolas have lower critical micelle concentrations and increased water solubility. Deciphering the self-assembly behavior of bolas will have great application potential in wide-ranging areas from material science to biology. This account describes the different types of self-assembled structures and their mechanistic pathways and presents the state of the art concerning sophorolipid (typical abolas and bio-surfactant) self-assembly.
