MICROFLUIDIC DEVICE WITH AUXILIARY AND BYPASS CHANNELS

摘要

The invention is directed to a microfluidic device having a flow inlet and outlet, generally defining a flow direction. A bypass channel (11) and an auxiliary channel (21) are provided which respectively defines a first and a second flow path toward the same outlet (102). The auxiliary channel connects to a reagent area (215), i.e., designed to receive a reagent (e.g., chemical or biological, such as detection antibodies). It further joins the bypass channel at the level of a junction (J1) downstream the reagent area, with respect to the second flow path, e.g., like a T- junction. Such a solution provides a simple way of adapting the dissolution rate of the reagent.
