Abstract
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.
