제목 pH and/or Temperature Responsive Micelles and Hydrogelsfor Drug Delivery and Molecular Imaging
초록 In this presentation, we would like to introduce some recent works on the pH and/or temperature responsive micelles and hydrogels for controlled drug delivery and molecular imaging applications.
Micelles
In our system, the pH-responsive polymeric micelles were composed of hydrophilic methyl ether poly(ethylene glycol) (MPEG) and pH-responsive degradable poly(β-amino ester) segments. This diblock copolymer, which could self-assemble nano-sized micelles with core-shell structures under aqueous conditions, showed noticeable the pH-dependent micellization-demicellization behavior.
Hydrogels
we have also investigated an injectable carrier of pH/ temperature sensitive hydrogel, penta-block copolymer PAE-PCL-PEG-PCL-PAE, for controlled drug/protein delivery. The cationic nature of PAE is used as the second function to make the ionic complexes with anionic biomolecule loaded into the hydrogel such as insulin. As a result, the release of drug/protein from this hydrogel device can be controlled by the degradation of copolymer.
