Abstract:
A method of separating a plurality of particles ( 14 ) from a portion of fluid, comprising directing the plurality of particles ( 14 ) into a microchannel ( 12 ). A first portion ( 16 ) of particles ( 14 ) is focused into an equilibrium position in the microchannel ( 12 ). The focused first portion ( 16 ) is directed into a first outlet ( 18 ) aligned with the equilibrium position. A portion of the fluid is directed into one or more outlets ( 20, 22 ). A microfluidic device ( 10 ) for separating a plurality of particles ( 14 ) from a portion of fluid, comprising a microchannel ( 12 ) having a first aspect ratio and a length L, thereby focusing the particles ( 14 ) directed therein into an equilibrium position in the microchannel, wherein at least a first portion ( 16 ) of the particles ( 14 ) focuses at distance X from a beginning of the microchannel ( 12 ). A first outlet ( 18 ) disposed after distance X and aligned with the equilibrium position to receive at least the first portion ( 16 ) of the particles ( 14 ) after the first portion ( 16 ) focuses into an equilibrium position in the microchannel ( 12 ). At least a second outlet ( 20 ) for receiving a second portion of the particles ( 14 ) before the second portion focuses into an equilibrium position.

Claim (Index 1):
A microfluidic device for separating a plurality of particles from a fluid medium, comprising:\n a microchannel having a first aspect ratio and a length L 1  in order to allow the particles directed therein to focus into a first equilibrium position in the microchannel, and a chamber in fluid communication with the microchannel and having a second aspect ratio, the chamber further comprising:\n a first capture portion having a first chamber outlet, the first chamber outlet being separated from the microchannel by a first wall, \n a second capture portion symmetric with the first capture portion, the second capture portion having a second chamber outlet, the second chamber outlet being separated from the microchannel by a second wall, \n a main outlet in a third wall opposite the first and second walls, and \n a main flow area in the chamber between the microchannel and main outlet, the main flow area also defined as being between the first and second capture portions; \n wherein:\n upon entering the chamber, the equilibrium position of the particles changes and the particles experience a first migration away from a center axis of the chamber, \n when the first migration causes the particles to leave the main flow area, the particles migrate into the capture portions, \n when the particles remain in the main flow area during the first migration, the particles further experience a second migration towards a second equilibrium position and are directed into the main outlet; and \n first and second chamber outlets communicating with the first and second capture chambers, the first and second chamber outlets receiving particles that migrate into the first and second capture portions.
