Summary
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 that was insensitive for the external pH. The sensor was sucessfully utilized at pH 4 under anaerobic conditions in gel particles containing homogeneously dispersed immobilized yeast cells.
