Abstract

La présente invention concerne des systèmes microfluidiques reconfigurables basés sur des réseaux de cavités microfluidiques reliées par des canaux microfluidiques hydrophobes. Chaque cavité est catégorisée comme étant soit un réservoir soit un nud, et comprend un orifice de pression par lequel une pression de gaz peut être appliquée. Des séquences de pressions de gaz, appliquées à des réservoirs et des nuds en fonction d'une règle de transfert de fluide, permettent de déplacer un fluide depuis un quelconque réservoir jusqu'à un quelconque autre réservoir d'un système. Des systèmes peuvent être configurés avec de multiples régions d'interaction commutées connectées en série en vue de dosages immunologiques multiplexés échelonnables. Plusieurs régions d'interaction commutées peuvent également être mises en uvre avec des microvannes.
