Dual-responsive colloidal microcapsules based on host-guest interaction on solid templates

Recent advances in metallopolymer-based drug delivery systems

“…35 ). 244 In the drug-loading experiments, the rhodamine isothiocyanate labeled dextran ( M w 150 kDa) as a model was mainly encapsulated in the pores between NPs in the shell of MCs.…”

Responsive materials based on coordination bonds

“…This is because noncovalent interactions and dynamic covalent bonds are susceptible to dissociation in response to stimuli, which can lead to detectable macroscopic changes in materials properties. Dynamic covalent bonds such as disulfide bonds, [76‐79] borate ester bonds, [80‐84] Schiff base bonds, [85‐90] and noncovalent interactions such as coordination bonds, [91‐93] ionic bonds, [94‐96] hydrogen bonds, [97‐104] halogen bonds, [105,106] hydrophobic interactions, [107‐109] conjugated π – π stacking interactions, [110] electrostatic interactions, [111‐114] and host–guest interactions [115‐123] have shown to be effective in constructing stimuli‐responsive materials. Among them, coordination bonds, which form between a metal providing an empty orbital and a ligand providing lone pairs, are particularly interesting.…”

Supramolecular redox-responsive substrate carrier activity of a ferrocenyl Janus device

“…self-assembly behavior. Among various host-guest inclusion complexes, a typical β-CD/Fc-based molecular recognition system has been used to fabricate a plethora of supramolecular devices [33][34][35][36][37][38][39]. β-CD is a cyclic oligosaccharide composed of seven D-glucose repeating units coupled through α-1,4-glucosidic linkages [40][41][42], and it resembles a truncated-cone construction with hydrophilic outside surface and hydrophobic internal cavity on the truncated cone [40][41][42].…”
