A catalyst made from phosphate and a biosensor including the same.

摘要

The biosensor according to the present invention includes a catalyst made from phosphate for accelerating an equilibrium reaction between alpha -glucose and beta -glucose. Particularly, the biosensor of the present invention includes an electrically insulating substrate, an electrode system formed on the substrate having a working electrode and a counter electrode, and a reaction layer provided over the electrode system, and the reaction layer includes at least an enzyme, an electron acceptor and phosphate. According to the present invention, a substrate such as a saccharide contained in a sample liquid can be easily quantified with accuracy and speed.
