Multi-analyte system and method based on impedimetric measurements

摘要

The invention discloses a system for the simultaneous detection and/or quantification of various analytes in a sample or for the simultaneous detection and/or quantification of an analyte in various samples, comprising: a multi-electrode chip (10) comprising an array of microelectrodes (11a, 11b, 11c, 11d); a single-duct cell (20), comprising a groove (21) which accommodates the multi-electrode chip (10) and a duct (22) through which a fluid sample can sequentially flow through each of the microelectrodes (11a, 11b, 11c, 11d) of a multi-electrode chip (10) when the latter is inserted into the groove (21); and a multi-duct cell (30), comprising a groove (31) housing the multi-electrode chip (10) and several independent ducts (32a, 32b, 32c, 32d) through which several samples can pass independently through each electrode (11a, 11b, 11c, 11d) of the multi-electrode chip (10).

主权项

1. A multiple multi-analyte system based on impedimetric measurements for simultaneous detection and/or quantification of various analytes in a single sample or for the simultaneous detection of an analyte in various samples, comprising:
a multi-electrode chip comprising a set of microelectrodes; a single-duct cell, comprising a groove suitable for accommodating the multi-electrode chip and a single duct through which a fluid sample can sequentially flow through each of the microelectrodes of a multi-electrode chip when the latter is inserted in the groove; a second multi-duct cell, comprising a groove suitable for accommodating the multi-electrode chip and several independent ducts through which various fluid samples can flow independently through each microelectrode of the multi-electrode chip.
