Microfluidic system and method for arranging objects

Abstract:

Microfluidic systems and methods for arranging a set of objects. In an exemplary method, the set of objects may be transported in carrier fluid along a microfluidic channel structure having a reformatting zone including an object-accessible region and at least one object-excluding region. A portion of the carrier fluid may be moved from the object-accessible region to the at least one object-excluding region in an upstream section of the reformatting zone, to reduce a spacing of objects of the set. The portion of the carrier fluid may be directed into the object-accessible region from the at least one object-excluding region in a downstream section of the reformatting zone, to increase a spacing of objects of the set. The steps of moving and directing in combination may increase the spacing between objects disproportionately for a subset of the objects that are closest to one another.
