electrochemical detector to facilitate repeated measurements.

摘要

A description is made on an electrochemical sensor wherein FET (1, 3) for measuring chemical substances and a reference electrode (2) are covered with a continuous hydrous polymer (4) on an insulating substrate (20), and on the hydrous polymer (4), an enzyme-immobilized film (5) is formed in a region positioned on a channel part of FET (3) for measuring chemical substances.
