METHOD AND DEVICE FOR THE QUANTITATIVE ELECTRICAL DETECTION OF ANALYTES

摘要

The invention relates to a method for detecting one or more analytes by a recognition reaction, using a device with an electrolyte-filled electrolyte space, having at least one measurement electrode, optionally with an insulating region (insulator layer) next to th e measurement electrode, and recognition molecules which are immobilized on the measurement electrode and/or on the insulating region next to the measurement electrode, and a counterelectrode. The electrical conductance or the resistance between the measurement electrode/s and the counterelectrode is measured as a function of the development time, and the time profile of the conductance or the resistance is analyzed. The invention also relates to a device with which th e method according to the invention can be carried out.
