Title (EN) MICROFLUIDIC DEVICES AND METHODS OF PREPARING AND USING THE SAME
(FR) DISPOSITIFS MICROFLUIDIQUES ET LEURS METHODES DE PREPARATION ET D'UTILISATION
Abstract:
(EN) Microfluidic devices include a photoresist layer in which an inlet chamber, an optional reaction chamber and at least one detection chamber are in fluid contact, a support arranged under the photoresist layer and a cover arranged above the photoresist layer. The devices further include a set of absorbent channels downstream of the last detection chamber. Biogenic or immunoreactive substances are placed in the reaction chamber and detection chamber(s). When a liquid sample is dropped into the inlet chamber, the sample liquid is drawn through the devices by capillary action. Detection methods include electrochemical detection, colorimetric detection and fluorescence detection.
(FR) L'invention concerne des dispositifs microfluidiques comprenant une couche de photorésist dans laquelle une chambre d'entrée, une chambre de réaction éventuelle et au moins une chambre de détection sont en contact fluidique, un support agencé sous la couche de photorésist et un élément couvrant agencé sur la couche de photorésist. Les dispositifs de l'invention comprennent également un ensemble de canaux absorbants situés en aval de la dernière chambre de détection. Des substances biogènes ou immunoréactives sont placées dans la chambre de réaction et dans la ou les chambres de détection. Lorsqu'on dépose des gouttelettes d'échantillon liquide sur la chambre d'entrée, le liquide d'échantillon est aspiré par le dispositif par action capillaire. Des méthodes de détection de l'invention comprennent une détection électrochimique, une détection colorimétrique et une détection par fluorescence.
