<p>Apparatus method for performing an electrochemical assay or a reaction, using electrical conductivity and/or power in order either to perform a reduction or an oxidation or an ion transfer reaction, or to perform conductimetry and/or impedance measurements, or to generate an electric field in a solution, or to perform any combination of the aforesaid. The apparatus comprises at least one micro-chip (1) possessing a microstructure (2) (for example a micro channel or array or network of microchannels) having a tip end (3) adapted for uptake of a fluid sample into and/or discharge of a fluid sample from said microstructure, a microfluidic connection end (4) and an integral electrode. It also comprises a microfluidic control unit (11) communicating with the microfluidic connection end of the microstructure and adapted to push, pull or block fluids in the microstructure, and an electrochemical unit adapted to apply an electric field or a current to fluid in the microstructure and/or to measure an electrochemical event therein. Optionally, there is support means adapted to support the micro-chip(s) in relation to the microfluidic control unit in such a manner as to ensure fluid-tight connection therebetween.</p> |
