Abstract
It is an object of the present invention to provide a sensor, which is capable of measuring, quickly and in high accuracy, concentration of neutral fat from a sample such as a biological sample or the like, without executing pretreatment of the sample. This object is attained by a biosensor for measuring concentration of neutral fat, based on value of current flowing in the electrode system, having: an insulating substrate; an electrode system having a working electrode and a counter electrode, formed onto the insulating substrate: and a reaction layer having a lipoprotein lipase, a glycerol dehydrogenase and an electron mediator, formed at the upper part or the vicinity of the electrode system.
Claims16
A biosensor for measuring concentration of neutral fat, based on value of current flowing in said electrode system, comprising:
- an insulating substrate;
- an electrode system having a working electrode and a counter electrode, formed onto said insulating substrate;
- a reaction layer having a lipoprotein lipase, a glycerol dehydrogenase and an electron mediator, formed at the upper part or the vicinity of said electrode system;
- and
- a lead part and a connector part for making said electrode system electrically conducted to outside of the biosensor, wherein a material configuring said electrode system is a material of carbon, as a main component, with a surface resistivity value of equal to or lower than 100 Ω/□, in a thickness of 10 μm, a material configuring said lead part and said connector part is a material of metal, as a main component, with a surface resistivity value of equal to or lower than 50 Ω/□, in a thickness of 10 μm, and the glycerol dehydrogenase is pyrrolo-quinoline quinone dependent.
