Abstract
A microfluidic chip can comprise a body defining a microfluidic network having one or more inlet ports, a test volume, and one or more flow paths extending between the inlet port(s) and the test volume. Along each of the flow path(s), fluid can flow from one of the inlet port(s), through at least one droplet-generating region in which a minimum cross-sectional area of the flow path increases along the flow path, and to the test volume. The network can include a gutter disposed along at least a portion of the test volume's periphery. The gutter can have a depth along a trough that is at least 10% larger than the depth of the test volume at the periphery and a depth along a ridge disposed between the trough and the test volume that is less than the depth of the test volume at the periphery.
