The separate fields of conducting polymer based electrochemical sensors and virus based molecular recognition offer; numerous advantages for biosensing Grafting M13 bacteriophage into an array of poly (3 4 ethylenedioxythlophene) (PEDOT) nanowires generated hybrids of conducting polymers and viruses The virus incorporation into the polymeric backbone of PEDOT occurs during electropolymerization via lithographically patterned nanowire electrodeposition The resultant arrays of virus PEDOT nanowires enable real time reagent free electrochemical biosensing of analytes in physiologically relevant buffers
