TLDR
In this article, results and data are reported on key aspects of sample processing protocols performed on-chip in a digital microfluidic lab on-a-chip (LABON-A-chip).Abstract:
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 contaminationread more
