Stepwise and reversibly controlled release and capture of α-CD by Mg-CP in quasi-solid state. a Photograph of the polyacrylamide hydrogel. b Photograph of Mg-CP⊃α-CD incorporated into the polyacrylamide hydrogel. c A pictorial representation of Mg-CP⊃α-CD in the polyacrylamide hydrogel. d Temperature-dependent changes in the ICD spectra of the polyacrylamide hydrogel. e Temperature-dependent changes in the ICD spectra of the Mg-CP⊃α-CD entrapped polyacrylamide hydrogel. Changes in the ICD spectrum at 350 and 420 nm are represented by magenta and cyan lines, respectively. f Stepwise release profile of α-CD from Mg-CP monitored at 350 and 420 nm in the hydrogel at different temperatures. g Reversible binding (black arrow) and release (blue arrow) of α-CD from Mg-CP incorporated into the hydrogel
