Electrochemical biosensor comprising carbon nanotube for measuring biosignals and method for manufacturing same

The present invention provides an electrochemical biosensor comprising a carbon nanotube for measuring biosignals. The electrochemical biosensor for continuous glucose monitoring comprises an electrode to which a sensing film including an oxidoreductase, an electron transfer mediator, and a crosslinker is fixed, together with a carbon nanotube. Wherein the carbon nanotube is comprised in an amount of 1 to 20 % by weight based on the total weight of the sensing membrane, the electron transfer mediator comprises a metal complex comprising one kind of transition metal selected from the group consisting of Os, Rh, Ru, Ir, Fe and Co and a monodentate or multidentate ligand, and a polymer backbone; and the carbon nanotube is a single-walled carbon nanotube, a multi-walled carbon nanotube or a blend of a single-walled carbon nanotube and a multi-walled carbon nanotube the oxidoreductase oxidizes a target substance and the electron thus generated in the oxidation process is transferred through the electron transfer mediator and the carbon nanotube, whereby the electrochemical biosensor can be used as a sensor having an excellent performance for continuous glucose monitoring.
