Electrowetting-based on-chip sample processing for integrated microfluidics

In this work, results and data are reported on key aspects of sample processing protocols performed on-chip in a digital microfluidic lab-on-a-chip. We report the results of experiments on aspects of sample processing, including on-chip preconcentration and dilution, on-chip sample injection or dispensing, and sample mixing. It is shown that high speed transport and mixing of analytes and reagents can be performed using biological solutions without system contamination.
