METHOD AND APPARATUS FOR ELECTROCHEMICAL IMMUNOASSAY

摘要

A method of electrochemical alkaline phosphatase immunoassay comprises the steps of: contacting the alkaline phosphatase with 1-naphthyl phosphate allowing the phosphatase to hydrolyse the 1-naphthyl phosphate to form 1-naphthol and detecting the electrochemical oxidation potential of said 1-naphthol using an electrode comprising resin bonded particles of carbon having a particle size of 3 to 50 nm the particles carrying a platinum group metal.
