Abstract:
    Motile particles are sorted from non-motile particles in a microfluidic sorting device (10) wherein a stream of sort fluid from a sort stream channel (7) containing mobile and non-motile particles is caused to flow adjacent a media stream from a media stream channel (8) in non-turbulent fashion through a sort channel (6), during which flow motile particles cross the interface between the adjacent flow streams, entering the media stream, and forming a motile particle depleted sort stream in a motile particle depleted sort channel (9). The sorting devices are easily and inexpensively fabricated and have numerous uses, in particular sorting of motile from non-motile sperm.
