Abstract

L'invention concerne un dispositif microfluidique comprenant plusieurs structures de microcanaux qui présentent un port d'entrée, un port de sortie et, entre les deux, une sous-structure comportant une fonction fluidique. Ce dispositif a un axe de symétrie autour duquel les structures de microcanaux sont disposées sous forme d'au moins deux zones annulaires concentriques. S'agissant d'un port d'entrée et d'un port de sortie de cette structure de microcanaux, le port d'entrée est généralement plus proche de l'axe de symétrie que n'est le port de sortie. Chaque structure de microcanaux comprend une sous-structure qui peut retenir un liquide lorsque le disque est tourné autour de l'axe et/ou les ports d'entrée étant positionnés séparément des voies, les résidus liquides laissant ouverts les ports de sortie de déchets traversent la surface du disque lorsque ce dernier est tourné. Pour les structures de microcanaux d'une zone annulaire, les sous-structures correspondantes sont sensiblement à la même distance radiale tandis que les sous-structures correspondantes des structures de microcanaux de différentes zones annulaires sont à différentes distances radiales. L'invention concerne également plusieurs autres sous-structures. Les sous-structures sont principalement adaptées au transport d'aliquots liquides ayant une tension superficielle > 5 mN/m avec une force centrifuge.
