We report a multi-stimuli responsive supramolecular hydrogel with great potential for biomedical application, which was composed of the micelle-forming diblock copolymer and physically cross-linked by complexation between ferric ions and carboxylic acid groups, exhibiting gel–sol transition caused by UV irradiation, multidentate ligands (EDTA) and redox agents (Na2S2O4).

AbstractWe present a comprehensive study of using diblock copolymer micelle templates to synthesize ordered nanoparticle arrays. Ionic and coordination bonds have been exploited to incorporate nanoparticle precursors into cores of block copolymer micelles. Polystyrene-b-poly (4-vinylpyridine) (PS-b-P4VP) has been shown to be able to localize anions via electrostatic attraction with protonated pyridine cations while transitional metals can be sequestered through coordination bonds. Polystyrene-b-poly (acrylic acid) (PS-PAA) can localize a variety of cations via ionic bonds with acrylic anions. We have demonstrated that the size of nanoparticles can be tuned by controlling the solution concentration of an ionic precursor. By mixing these two distinct block copolymers which can selectively interact with different precursor species, complex nanoparticle architectures can be generated thus paving a path for new applications.
