Abstract[English]
A target molecule detection method includes contacting oxidation and reduction electrodes with a solution having redox tags. The method further includes applying a first oxidation voltage pulse to the oxidation electrode when the solution does not contain the target molecules to obtain a first oxidation current profile, applying a second oxidation voltage pulse to the oxidation electrode when the solution contains the target molecules to obtain a second oxidation current profile, applying a first reduction voltage pulse to the reduction electrode when the solution does not contain the target molecules to obtain a first reduction current profile, and applying a second reduction voltage pulse to the reduction electrode when the solution contains the target molecules to obtain a second reduction current profile. The method also includes detecting the target molecules in response to one or more electrical properties of the first and second oxidation and reduction current profiles.[French]
L'invention concerne un procédé de détection de molécule cible, comprenant la mise en contact d'électrodes d'oxydation et de réduction avec une solution contenant des marqueurs d'oxydoréduction. Le procédé comprend en outre l'application d'une première impulsion de tension d'oxydation à l'électrode d'oxydation lorsque la solution ne contient pas de molécules cibles afin d'obtenir un premier profil de courant d'oxydation, l'application d'une seconde impulsion de tension d'oxydation à l'électrode d'oxydation lorsque la solution contient des molécules cibles afin d'obtenir un second profil de courant d'oxydation, l'application d'une première impulsion de tension de réduction à l'électrode de réduction lorsque la solution ne contient pas de molécules cibles afin d'obtenir un premier profil de courant de réduction, et l'application d'une seconde impulsion de tension de réduction à l'électrode de réduction lorsque la solution contient des molécules cibles afin d'obtenir un second profil de courant de réduction. Le procédé consiste également à détecter les molécules cibles en réponse à une ou plusieurs propriétés électriques des premier et second profils de courant d'oxydation et de réduction.
