Claim 14:
15. The microfluidic device of claim 14, wherein the second particle sorting region comprises:
a third array of islands separating a fourth microfluidic channel from a fifth microfluidic channel parallel to the fourth microfluidic channel, wherein each island in the third array is separated from an adjacent island in the third array by an opening that fluidly couples the fourth microfluidic channel to the fifth microfluidic channel;
a fourth array of islands separating the fourth microfluidic channel from a sixth microfluidic channel, wherein each island in the fourth array is separated from an adjacent island in the fourth array by an opening that fluidly couples the fourth microfluidic channel to the sixth microfluidic channel;
wherein the fourth microfluidic channel, the fifth microfluidic channel, and the third array of islands are configured to decrease a fluidic resistance of the fifth microfluidic channel along a longitudinal direction of the second particle sorting region relative to the fluidic resistance of the fourth microfluidic channel;
wherein the fourth microfluidic channel, the sixth microfluidic channel, and the fourth array of islands are configured to increase a fluid resistance of the sixth microfluidic channel along the longitudinal direction of the second particle sorting region relative to the fluidic resistance of the fourth microfluidic channel; and
wherein the third array of islands and the fourth array of islands are parallel to each other, and each array of islands is oriented in the longitudinal direction of the second particle sorting region.
