Enhanced Electron Transfer from Glucose Oxidase to DNA-Immobilized Electrode Aided by Ferrocenyl Naphthalene Diimide, a Threading Intercalator

Abstract
A ferrocene-modified 1,4,5,8-naphthalenetetracarboxyldiimide (1), bound to double stranded DNA by a threading intercalation mode, enhanced the electron transfer between glucose oxidase and a DNA-immobilized electrode.
