More Information
Summary:A microfluidic device includes a chamber having a floor, a ceiling, and an inlet. The microfluidic device includes pillars extending from the floor to the ceiling of the chamber. Each pillar has a leading surface or corner, a trailing surface or corner opposite the leading surface or corner, and trailing side surfaces adjoining the trailing surface or corner. Each pillar is oriented along a corresponding ray intersecting the leading surface or corner and the trailing surface or corner. Adjacent pillars have a turn angle between the corresponding rays of the adjacent pillars, and each pillar has a pillar angle between the trailing side surfaces thereof. The turn and pillar angles are based on a fluidic contact angle to promote fluid flow from the inlet throughout the chamber during priming without fluidic pinning.
