A microfluidic system configured to focus particles suspended in a fluid. One general aspect includes a microfluidic system comprising one or more substrates and a focusing channel formed in the one or more substrates and spanning a length from an inlet to an outlet for receiving a flow of particles suspended in fluid, wherein the particles have a diameter (a) and the focusing channel has a hydraulic diameter (dh).

Systems and methods for particle focusing in microchannels

Microfluidic devices and methods for focusing components in a fluid sample are described herein. The microfluidic devices feature a microfluidic chip having a micro-channel having a constricting portion that narrows in width, and a flow focusing region downstream of the micro-channel. The flow focusing region includes a positively sloping bottom surface that reduces a height of the flow focusing region and sidewalls that taper to reduce a width of the flow focusing region, thereby geometrically constricting the flow focusing region. The devices and methods can be utilized in sex-sorting of sperm cells to improve performance and increase eligibility.

Single-sheath microfluidic chip

Microfluidic devices and methods for focusing components in a fluid sample are described herein. The microfluidic device has at least one flow focusing channel where the components are focused or re-oriented by the geometry of the channel. From an upstream end of the flow focusing channel to a downstream end of the flow focusing channel, at least a portion of the flow focusing channel has a reduction in height and at least a portion of the flow focusing channel narrows in width, thereby geometrically constricting the flow focusing channel. The devices and methods can be utilized in sex-sorting of sperm cells to improve performance and increase eligibility.
