摘要:
Compositions and methods for electrochemical detection of nucleic acid are disclosed. The compositions comprise electrocatalytic intercalators that bind to double-stranded nucleic acid and oxidize nucleic acid. Methods of detecting nucleic acid in a sample comprise forming double-stranded nucleic acid that is bound by electrocatalytic intercalators wherein the intercalators catalyze oxidation of the nucleic acid at the surface of an electrode.

摘要:
There is provided an electrochemical assay method for detecting a target molecule, for example a protein, in a sample, which involves the use of a protective monolayer and a redox polymer to form a bilayer immobilized on an electrode. The monolayer protects the electrode from non-specific adherence of reagents, particular proteins, to the electrode while simultaneously providing a surface that can be functionalized to immobilize a capture molecule and that can interact with the redox polymer.
