摘要
The disclosure relates to an apparatus for segregating particles on the basis of their ability to flow through a stepped passageway. At least some of the particles are accommodated in a passage bounded by a first step, but at least some of the particles are unable to pass through a narrower passage bounded by a second step, resulting in segregation of the particles. The apparatus and methods described herein can be used to segregate particles of a wide variety of types. By way of example, they can be used to segregate fetal-like cells from a maternal blood sample such as maternal arterial blood.
