Abstract
A microfluidic device including at least one channel in fluid communication with a sample trap array. Specifically, the configuration and geometry of the trap arrays according to the present invention allows for performing sample digitization that supports passive self-discretization within the sample traps without the need for any external flow control or actuation. Geometrical parameters defining the sample traps, including the trap width and the trap depth, are selected to optimize self-filling of the sample traps. Reagents are incorporated into the sample traps during device fabrication to allow for performing multiplexed reactions within the sample traps.
