Microfabricated sensor arrays for multi-component analysis in minute volumes

摘要

Sensors and methods of making the same are disclosed. Sensors are microfabricated with multiple working electrodes and a single, common counter electrode. The multiple working electrodes can be fabricated in different geometrical configurations for advantageously analyzing multiple components simultaneously in the same microcell sensor. Furthermore, sensors according to certain embodiments of the invention include openings to allow photometric analysis along with electroanalytical methods.
