The stability of phospholipid and biomimetic polymer vesicles
… Z (AqpZ). PMOXA-PDMS-PMOXA (ABA) triblock co-polymers have demonstrated similar properties as phospholipids and incorporate AqpZ. Previous research conducted on AqpZ:ABA vesicles showed permeabilities exceeding commercial RO membranes and high selectivity. These properties make biomimetic …

Functional particles for controlled release and cell surface engineering
Engineered polymer vesicles (polymersome) have emerged as the new generation of molecular and cell carriers for a series of biomedical applications. These polymer vesicles typically present as hollow spheres that contain a hydrophilic core surrounded by a hydrophobic membrane, each of which can be …

Development of Soft-Matter Delivery Systems: Coupling pH Responsive Polymers to Porous Silica Particles
<p>This work investigates polymeric coating of evaporated induced self-assembly (EISA) mesoprous silica nanoparticles for potential use in controlled drug release and therapeutics. As demonstrated here, lipid bilayer coatings can be easily replaced with different polymer analogs allowing for …

Nanoemulsion-like Polymersomes for Nanoreactors
Self-assembly of block copolymers in various selective solvents provides a means to control nanostructures. Among selective solvents, ionic liquids (ILs) are of great interest as reaction media, with the possibility of replacing organic solvents. However, the implementation ILs is limited by their …

Biomimetic membranes as new materials for applications in envrionmental engineering and biology
… than that used in commercial solute separation polymeric membranes such as Reverse Osmosis (RO) membranes. In this work, the bacterial Aquaporin (AqpZ) was functionally incorporated into synthetic biomimetic polymer vesicles. Using stopped flow light scattering, the permeability of such systems …

Engineered Vesicles for Perchlorate Degradation
This study demonstrates the use of engineered vesicles to reduce perchlorate. Specifically, cell-free extracts containing perchlorate reductase and chlorite dismutase enzymes were encapsulated in a triblock copolymer vesicle functionalized with the outer membrane porin OmpF. The porin allows for …
