A microfluidic chip that can mimic the functions of a centrifuge without moving parts or external forces has been designed by Dino Di Carlo and colleagues from the University of California, Los Angeles. The Centrifuge-on-a-Chip uses fluid vortices to trap cells, and has been demonstrated to be effective in enriching rare cells from heterogeneous solutions and for performing labelling assays on-chip.
