Title (EN) MICROFLUIDIC STRUCTURE AND PROCESS FOR ITS MANUFACTURE
(FR) STRUCTURE MICROFLUIDIQUE ET PROCEDE POUR SA FABRICATION
Abstract:
(EN) A microfluidic structure comprises first and second substantially planar form-stable base layers (1, 2), and an intermediate spacing layer (3) of elastic material, said spacing layer (3) being recessed to define a microcavity or channel system (4) with at least one of said first and second base layers. The structure is produced by moulding the spacing layer, optionally applied to or integral with a first base layer (2), against a planar mould, and the microcavity or channel system is completed by applying a second base layer (1), and optionally said first base layer (2), to the spacing layer (3).
(FR) Une structure microfluidique comprend une première et une seconde couches de base pratiquement planaires et de forme stable (1, 2), et une couche de séparation intercalaire (3) composée d'un matériau élastique, ladite couche de séparation (3) étant en retrait pour délimiter une micro-cavité ou un système de canaux (4) avec au moins l'une desdites première et seconde couches de base. On produit la structure en moulant la couche de séparation, éventuellement appliquée sur la première couche de base ou incorporée à celle-ci (2), dans un moule planaire, et on forme la micro-cavité ou le système de canaux en appliquant une seconde couche de base (1) et éventuellement ladite première couche de base (2) sur la couche de séparation (3).
