Title (EN) METHOD AND APPARATUS FOR MANIPULATING POLARIZABLE ANALYTES VIA DIELECTROPHORESIS
(FR) PROCEDE ET APPAREIL DE MANIPULATION D'ANALYTES POLARISABLES PAR DIELECTROPHORESE
Abstract: front page image
(EN)The present invention is directed to devices and methods for manipulating polarizable analytes via dielectrophoresis to allow for improved detection of target analytes. Microfluidic devices (405) are configured such that the application of a voltage between field-generating electrodes (420, 421) results in the generation of an asymmetric electric field within the device (405). Some embodiments of the invention provide a physical constriction (410), and electrically floating conductive material (430) or a combination of the two techniques to generate an asymmetrical field. Using dielectrophoresis, target analytes are concentrated or separated from contaminant analytes and transported to a detection module (440).
(FR)La présente invention concerne des dispositifs et des procédés de manipulation d'analytes polarisables par diélectrophorèse afin de permettre la détection améliorée d'analytes cibles. Des dispositifs microfluidiques sont conçus de telle sorte que l'application d'une tension entre des électrodes génératrices de champs entraîne la génération d'un champ électrique asymétrique dans le dispositif. Certains modes de réalisation de l'invention font appel à un étranglement physique et à un matériau électroconducteur flottant ou à une combinaison des deux techniques afin de générer un champ asymétrique. L'utilisation de la diélectrophorèse permet de concentrer ou de séparer les analytes cibles des analytes contaminants et de les transporter vers un module de détection.
