Paramagnetic Porous Polymersomes
The ability of chelated Gd to serve as an effective magnetic resonance (MR) contrast agent largely depends on fast exchange rates between the Gd-bound water molecules and the surrounding bulk water. Because water diffuses slowly across lipid bilayers, liposomes with encapsulated chelated Gd have not been widely adopted as MR contrast agents. To overcome this limitation, we have synthesized chem...
متن کاملPolymersomes.
Polymersomes are self-assembled polymer shells composed of block copolymer amphiphiles. These synthetic amphiphiles have amphiphilicity similar to lipids, but they have much larger molecular weights, so for this reason--along with others reviewed here--comparisons of polymersomes with viral capsids composed of large polypeptide chains are highly appropriate. We summarize the wide range of polym...
متن کاملEnzymes containing porous polymersomes as nano reaction vessels for cascade reactions.
Polystyrene(40)-b-poly(isocyanoalanine(2-thiophen-3-yl-ethyl)amide)(50) (PS-PIAT) polymersomes have the unique property of being sufficiently porous to allow diffusion of small (organic) substrates while retaining large biomolecules such as enzymes inside. Herein we report on the encapsulation and protection of glucose oxidase (GOx) and horse radish peroxidase (HRP) in PS-PIAT polymersomes and ...
متن کاملPolymersomes in polymersomes: multiple loading and permeability control.
Polymer vesicles polymersomes are vesicles obtained from the self-assembly of amphiphilic block copolymers in aqueous solution as a result of free-energy minimization. Their potential use as drug delivery systems, sensors, and/or nanoreactors has recently attracted a great deal of interest. Polymersomes exhibit larger mechanical stability and lower permeability than liposomes, their structural ...
متن کاملA simple method for the synthesis of porous polymeric vesicles and their application as MR contrast agents.
Because of their low membrane permeability the use of polymeric vesicles in certain drug delivery and molecular imaging applications and as bioreactors is less than ideal. Here, we report a simple method to prepare porous polymeric vesicles that possess high membrane permeability. Specifically, porous vesicles were produced from the aqueous assembly of the diblock copolymer PEG-PBD, and the tri...
