Descrizione

Applicazioni

β-Cyclodextrin, a water-soluble cyclic oligosaccharide consisting of seven α-(1,4)-linked glucopyranose subunits,[1][2] is used in the preparation of:

• Linear cationic β-cyclodextrin-based polymers (β-CDPs) and polycationic β-cyclodextrin ‘click clusters′ for gene delivery applications.[3][4]
• Multiresponsive supramolecular nanogated ensemble by grafting onto mesoporous silica for controlled release of trapped molecules.[5]
• EDTA-cross-linked β-cyclodextrin (EDTA-β-CD) bifunctional adsorbent for simultaneous adsorption of metals and dyes.[6]
• β-Cyclodextrin derived siRNA delivery vector for gene silencing.[7]
• β-CD chiral stationary phase (CCNCSP) for the enantioseparation of chiral drugs by high-performance liquid chromatography (HPLC).[8]
