A new transducer concept for miniaturized immobilized enzyme glucose s
ensors is presented. The enzyme containing membrane is anchored inside
the microcontainment of a silicon chip together with the metal electr
ode. Containment based sensors are ideally suited for integration into
microsystems. The fabrication process is planned as a full wafer proc
ess allowing transfer to low-cost mass-production with a narrow variab
ility. The functionality of the containment concept is demonstrated by
the fabrication of chips with single GOD-based amperometric glucose s
ensors which have been tested in glucose solution. The advantages of t
he containment technology are discussed.
