Stimuli-induced gel-sol transition of multi-sensitive supramolecular beta-cyclodextrin grafted alginate/ferrocene modified pluronic hydrogel

This paper studies a kind of biocompatible hydrogel composed of alginate-g-beta-cyclodextrin (Alg-beta-CD) and ferrocene-terminated pluronic F127 (F127-Fc), which showed gel-sol phase transformations in response to temperature, oxidizing agents, and glucose because of the reversible association-dissociation of Fc-beta-CD inclusions and F127 micelles.
