▎ 摘　　要

NOVELTY - The method involves applying a specimen sample to each cell of a microelectrode array chip in which bio-molecules are not labeled; electrochemically measuring oxidation-reduction reactions in a biological specimen including independent cells by microelectrodes; applying energy to the microelectrode array chip such that different energies are applied to each cell; measuring an electrochemical signal in each cell; and comparing a measuring result with electrochemical signal data from the chip for normal and disease classification; and forming a catalyst layer of a carbon-based material-metal or carbon-based material-metal oxide complex on a working electrode of the microelectrode, where the carbon-based material is selected from activated carbon, graphene, and carbon nanotubes, and the metal oxide is selected from a group consisting of magnesium, titanium, zirconium, zinc, manganese, gold, silver, platinum, palladium, cobalt, copper, iron, nickel, tin, indium, vanadium, and chromium. USE - Method for providing information for diagnosing and predicting health condition using a microelectrode array chip. ADVANTAGE - The microelectrode array chip is economical.
