Abstract
A new-type glucose sensor using a LaF3-based transducer was investigated as the first example of a solid-electrolytecoupled biosensor. The sensor element was composed of the following electrochemical cell: (reference electrode) Sn+SnF2∣LaF3∣Pt-glucose oxidase (sensing electrode). The e.m.f. of the sensor cell was found to vary logarithmically with a change in glucose concentration in the range from 2×10-5 to 1×10-2 M in a phosphate buffer solution of pH 6.9. The 90% response time to 3×10-2 M glucose was about 15 s at 30°C. The sensitivity of the sensor to glucose was fairly stable for the test period of about 30 days.Keywords
