Abstract

Miniature PO₂ and pH sensors can be used in combination with enzymatic catalysts such as glucose oxidase and glucose dehydrogenase as the basis for the development of a small glucose sensor. The applications of microelectronic techniques such as photolithography techniques and thick- and thin-film metallization are novel approaches in fabricating highly uniform and reproducible sensors that are relatively simple to calibrate and operate.
