Integrated on-chip system for DNA purification, labelling and surface stretching
We report a simplified, integrated and more efficient way of preparing DNA for analysis. We have developed a microfluidic platform that can purify DNA and subsequently label and stretch it on a surface. We have successfully extracted DNA from a gel-filled microfluidic channel using electrophoresis and subsequently stretched the DNA linearly by absorption to either a hydrophobic or a positively-cha
