Antibodies raised against the conducting polymer, carbazole as a hapten, react to modulate the polymer's electrochemistry. Using cyclic voltammetry the reaction of the antiserum was discovered to influence the polymer matrix's electrochemistry by an amperometric response. It is suggested that these observation form the basis of a direct sensor for immunoassay.
