Abstract

Provided herein is a method for detecting mutations in polynucleotide sequences through the use of a glassy carbon electrode (GCE) coated with a chitosan-graphene nanosheet material (also referred to herein as a 'CMG electrode.') It is a surprising finding of the present invention that the CMG electrodes can be used to detect non-hybridization of capture and target polynucleotides using voltammetry, wherein non-hybridization indicates a mutation or difference in the target polynucleotide as compared to a control.
