Claim 0:
1. A microfluidic device, comprising:
a particle sorting region, comprising:
a first array of islands separating a first microfluidic channel from a second microfluidic channel parallel to the first microfluidic channel, wherein each island in the first array is separated from an adjacent island in the first array by an opening that fluidly couples the first microfluidic channel to the second microfluidic channel;
a second array of islands separating the first microfluidic channel from a third microfluidic channel, wherein each island in the second array is separated from an adjacent island in the second array by an opening that fluidly couples the first microfluidic channel to the third microfluidic channel;
wherein the first microfluidic channel, the second microfluidic channel, and the first array of islands are configured to decrease a fluidic resistance of the second microfluidic channel along a longitudinal direction of the particle sorting region relative to the fluidic resistance of the first microfluidic channel;
wherein the first microfluidic channel, the third microfluidic channel, and the second array of islands are configured to increase a fluidic resistance of the third microfluidic channel along the longitudinal direction of the particle sorting region relative to the fluidic resistance of the first microfluidic channel; and
wherein the first array of islands and the second array of islands are parallel to each other, and each array of islands is oriented in the longitudinal direction of the particle sorting region.
