Abstract
An ion-sensitive field-effect transistor (ISFET) glucose sensor with a new membrane structure is fabricated and its characteristics are evaluated in continuous measurement of non-diluted serum glucose. This sensor chip is composed of two ISFETs and a gold electrode. An albumin—glutaraldehyde crosslinked membrane, patterned on one of the ISFET gates and the gold electrode, contacts an enzyme membrane deposited on the other gate in edge to edge. Making an electrical connection between the gold electrode and two ISFETs, this membrane enables stable sensor responses to be made. This sensor is mounted on a flow cell into which serum samples and air are alternately fed. The sensor output shows a good linear relationship, up to 300 mg dl −1 glucose, and correlates well with a conventional glucose analyzer. This sensor shows promise as a key device in the development of portable glucose monitors.
