Abstract

A system, method and apparatus employing the laminar nature of fluid flows in microfluidic flow devices in separating, sorting or filtering colloidal and/or cellular particles from a suspension in a microfluidic flow device is disclosed. The microfluidic flow device provides for separating a particle within a suspension flow in a microfluidic flow chamber. The chamber includes a microfluidic channel comprising at least one inlet port for receiving a suspension flow under laminar conditions, a first outlet port and a second outlet port. The chamber further includes an interface for translating a particle within the channel. The first outlet port receives a first portion of the suspension exiting the said channel and the second outlet port receives the particle in a second portion of the suspension exiting the channel.
