Synthetic polyion-counterion transport systems in polymersomes and gels.
Transport across the membranes of polymersomes remains difficult in part due to the great thickness of the polymer bilayers. Here, we report that dynamic polyion-counterion transport systems are active in fluorogenic polymersomes composed of poly(dimethylsiloxane)-b-poly(2-methyloxazoline) (PDMS-PMOXA). These results suggest that counterion-activated calf-thymus DNA can act as cation carrier th...
متن کاملPolymer nanoreactors shown to produce and release antibiotics locally.
We designed and prepared nanoreactors based on a poly(2-methyloxazoline)-block-poly(dimethylsiloxane)-block-poly(2-methyloxazoline (PMOXA-b-PDMS-b-PMOXA) amphiphilic triblock copolymer encapsulating the enzyme penicillin acylase for local and controlled production of antibiotics.
متن کاملIn vitro expressed GPCR inserted in polymersome membranes for ligand-binding studies.
The dopamine receptor D2 (DRD2), a G-protein coupled receptor is expressed into PBd(22)-PEO(13) and PMOXA(20)-PDMS(54)-PMOXA(20) block copolymer vesicles. The conformational integrity of the receptor is confirmed by antibody- and ligand-binding assays. Replacement of bound dopamine is demonstrated on surface-immobilized polymersomes, thus making this a promising platform for drug screening.

Hybrid nanocapsules: interactions of ABA block copolymers with liposomes.
Amphiphilic ABA triblock copolymers, such as poly(2-methyloxazoline)-block-poly(dimethylsiloxan)-block-poly(2-methyloxazoline) (PMOXA-PDMS-PMOXA), form vesicular structures. Here, the interaction of these ABA molecules with lipids is investigated by electron microscopy, fluorescence spectroscopy, light scattering, and differential scanning calorimetry. Our observations suggest the formation of ...
