1. A particle sorting cartridge, comprising:
a sorting region comprising an intersection of:
a first microfluidic channel leading from a sensing region;
a second microfluidic channel leading from a trigger inlet and substantially perpendicular to the first microfluidic channel at the intersection;
a default branch channel leading away from the intersection and operably associated with the first microfluidic channel at the intersection; and
a selected branch channel leading away from the intersection at an angle acute to the default branch channel at the intersection, wherein the selected branch channel leads to a carrier channel connecting a carrier inlet to a sample collection outlet;
wherein the first microfluidic channel, the second microfluidic channel, and the default branch channel have substantially the same diameter at the intersection and the selected branch channel has a narrower diameter than the first microfluidic channel at the intersection; and
wherein the sorting region is configured to direct a sample liquid from the sensing region to the default branch channel in absence of a threshold flow of trigger fluid from the trigger inlet through the second microfluidic channel and further configured to direct the sample liquid from the sensing region to the selected branch channel during application of the threshold flow of trigger fluid from the trigger inlet through the second microfluidic channel.
