文摘
A facile strategy for preparing water-soluble β-cyclodextrin derivative, carbonyl-β-cyclodextrin, was developed by partial oxidation of β-cyclodextrin. The solubility of carbonyl-β-cyclodextrin was greatly enhanced due to the breaking of intramolecular hydrogen bond network of β-cyclodextrin. Ferrocene was included into the cavity of carbonyl-β-cyclodextrin to form Fc-carbonyl-β-cyclodextrin inclusion complex. The electrochemical properties of Fc-carbonyl-β-cyclodextrin were studied. The Fc-carbonyl-β-cyclodextrin complex exhibited high solubility and was shown to be good electrochemical probe and efficient mediator for bioelectrocatalysis of glucose oxidase. The bioelectrocatalytic efficacy of Fc-carbonyl-β-cyclodextrin complex opened up homogeneous applications of ferrocene in amperometric biosensor systems.
