Abstract

Close
- High throughput in particle and molecular sorting schemes is an important performance indicator and can be realized through increased volumetric processing rates or increased concentrations. Here we investigate the effect of increased concentration of high-molecular weight DNA in micropillar arrays for deterministic lateral displacement (DLD). We find that the array imposes regular fluctuations in the concentration of the DNA if the sample concentration and flow rates exceed respective threshold values. We characterize the resulting concentration waves and study their influence on microsphere trajectories in the device. We expect our results to be relevant e.g. for sample preparation of cell lysates which can often be complicated by the release of chromosomal DNA.
