Monolayer and electrode for detecting a label-bearing target and method of use thereof

The method for detecting the electrode of with an antibody, wherein an electrode formed by the conductive performs the modification is a single-layer composition, one using the method for detecting electrode and molecule, such as other detecting nucleic acid or targets, comprising the receptor ligand, and antigen, or antibody. With a nucleic acid, or dye of the oligomeric nucleotide scout and obtaining the target acid from reaction is single-layer, wherein the hybridization in the modified surface and nucleic acid. The nucleic acid hybrid of with said oxidase in the reduction reaction for the hybridization of the nucleic acid is selected from one of the basic groups the transition metal complex reaction, detecting the oxidation reduction reaction; the oxidization for detecting the reduction reaction is determined nucleic acid presence or absence of.
