Abstract
An example microfluidic structure can include a first microfluidic channel segment in a first elevation plane, a second microfluidic channel segment in a second elevation plane, and a transverse microfluidic channel segment connecting the first microfluidic channel segment to the second microfluidic channel segment. An angled exterior wall segment can be at the transverse microfluidic channel segment. The angled exterior wall segment can be angled in the first or second elevation plane at an acute angle with respect to a direction of fluid flow through the first or second microfluidic channel segment. A fluid cross-sectional area can increase in the fluid flow direction along the angled exterior wall segment.
