Abstract (en)

[origin: WO9927367A1] The invention relates to a method for detecting analytes and to a device for carrying out the method, for use for analysis or diagnosis in the fields of chemistry, biochemistry, molecular genetics, food chemistry, biotechnology, the environment and medicine. Marker particles (5) with different electrical properties or a different relative permeability to those of the measuring solution (3) surrounding them are used to detect the analytes (8). The marker particles (5) either bond specifically to the analytes (8) or to a base (2) in competition with the analyte. The analytes (8) are detected by the changes in an electrical field or an electrical current generated by electrodes (2) or in an electrical voltage applied to an electrode or in a magnetic field, said changes being caused by marker particles which have bonded with the analytes or by marker particles which have instead bonded to the base in an electrical field.
