Method for studying enzymatic and other biochemical reactions
First Claim
1. Method for determining the activity of concentration in a sample, of a biochemical substance which biochemically affects a substrate that is specific for the biochemical substance which comprises:
- providing metallic or semiconductor electrodes coated with said substrate,determining as a control value, the capacitance in a measuring device of said metallic electrodes or semiconductor electrodes coated with said substrate,introducing the sample to be tested for the determination of the activity or concentration of said substance into said measuring device so as to contact said coated electrodes with said sample,measuring the change in capacitance due to a change in the amount of biochemically uneffected substrate coated on said electrodes, and thereby obtaining a quantitative measure of the activity or concentration of said substance, present in the sample and affecting the specific substrate on the electrodes.

Abstract
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.
