Patent ID: 10343161

Abstract:
The invention is directed to a microfluidic device. The device includes an input microchannel, a set of m distribution microchannels, a set of m microfluidic modules and a set of m nodes. The m microfluidic modules (m≥2) are in fluidic communication with the m distribution microchannels, respectively. The one or more nodes of the set of m nodes branch from the input microchannel, and further branch to a respective one of the set of m distribution microchannels. In addition, a subset, but not all, of the nodes are altered. The nodes of the set of m nodes have different liquid pinning strengths. As a result, the extent in which a liquid passes through one or more of the m microfluidic modules varies based on the different liquid pinning strengths, in operation. Additional sets of nodes may be provided to allow liquid to pass through ordered pairs of modules.
