Biomedical engineers Dr. Marnie Winter and Professor Benjamin Thierry from the University of South Australia's Future Industries Institute and the ARC Centre of Excellence in Convergent Bio-Nano Science and Technology are leading a team of researchers who used the microfluidic technology to isolate fetal cells for the first time.

The special design of the microfluidic device allows large volumes of blood to be screened, paving the way for an efficient, cheap and quick method of separating fetal cells from maternal blood cells.
