Cell sorting is of enormous importance in medical diagnostics and for applications in bionanotechnology in general. The implementation of cell sorters on small length scales in microfluidic systems is very useful because most biological materials are only available in tiny volumes. The reduction in sample size not only reduces costs dramatically but also enhances specificity. The microfluidics group of Thomas Franke in Augsburg has recently published a novel sorting scheme based on acoustics that can deflect cells at very high rates (LabChip 2009, LabChip 2010). In the project this microfluidic access shall be combined with a capacitive detections system developed in the lab of Prof. Andrew Cleland from the University of California in Santa Barbara. The combined hybrid device is expected to demonstrate a fast sorting device which sorts objects according to their relative permitivity.
