ELECTROCHEMICAL DETECTION OF A METAL - LABELLED ANALYTE

摘要

Disclosed is a method for determining the presence or amount of a metal-labelled analyte in a sample, the method including the steps of: adding a release agent to the metal-labelled analyte to release the metal label fromthe analyte, the release agent and the metal label together forming an insoluble charged species, applying a potential to bring the charged species to an electrode, applying a positive potential to the charged species to dissolve the metal label toform metal ions, and carrying out a quantitative determination procedure to determine the presence or amount of the metal-labelled analyte.
