Electrochemical immunosensor and kit and method for detecting biochemical anylyte using the sensor

Abstract

An electrochemical immunosensor including a biological sensor layer with an antigen or a ligand residue immobilized thereon, and a biochemical analyte detection kit and method for electrochemically signaling a biological reaction occurring in the biological sensor layer are provided. The electrochemical immunosensor includes a substrate, an electrode or an electrode array formed on the substrate, and a biological sensor layer formed on the electrode or the electrode array and including a polymeric dendrimer monolayer with an antigen or a ligand residue immobilized on the surface thereof. The biological sensor layer further includes an adhesive layer for biomolecular immobilization between the electrode and the polymeric dendrimer monolayer.
