Method for studying biochemical reactions in which a substance, whose activity or concentration is to be determined, affects a substrate specific for the biochemical reaction which includes providing electrodes coated with the substrate, determining as the control value, the capacitance in a measuring device containing the electrodes, introducing the substance into the measuring device, measuring the change in capacitance, and thereby obtaining a quantitative measure of the activity or concentration of the substance present in the sample and affecting the specific substrate on the electrodes.
