Enzyme-Modified Microelectrode for Simultaneous Local Measurements of O₂ and pH.

ABSTRACT: The use of miniaturized probes opens a new dimension in the analysis of (bio)chemical processes, enabling the possibility to perform measurements with local resolution. In addition, multiparametric measurements are highly valuable for a holistic understanding of the investigated process. Therefore, different strategies have been suggested for simultaneous local measurements of various parameters. Electroanalytical methods are a powerful strategy in this direction. However, they have been mainly restricted to coupling concurrent independent measurements with different miniaturized probes. Here, we present an enzymatic microbiosensor for the simultaneous detection of O₂ and pH. The sensing strategy is based on the pH-dependent bioelectrocatalytic process associated with O₂
