Direct measurement of glucose profiles in immobilized yeast gels with a pH-insensitive micro-electrode under anaerobic conditions

A 10 µm glucose sensor was developed based on a glucose oxidase coated Pt-electrode inserted in a capillary shaft. The internal buffer medium effected in a glucose response that was insensitive for the external pH. The sensor was successfully utilized at pH 4 under anaerobic conditions in gel particles contg. homogeneously dispersed immobilized yeast cells. [on SciFinder (R)
