The method for detecting an analyte of the present invention comprises the steps of: coating an electrode with at least one of an aniline polymer formed by substituting hydrogen of a monomer with a boric acid, followed by electropolymerization, a thiopene polymer, a pyrrole polymer, a carbon nanotube and graphene; exposing the electrode to an analyte that is present in a solution or air; and measuring impedance generated from the electrode exposed to the analyte. The present invention forms the aniline polymer by electropolymerization of an aniline monomer which is formed by substituting hydrogen with a boric acid in the step of coating the electrode, and utilizes the electrode as a biosensor after coating the electrode with the aniline polymer. Further, in the step of measuring impedance, the presence/absence of an analyte is detected from a change in conductivity.
