Nanofluidic devices towards single DNA molecule sequence mapping

Abstract

Nanofluidics enables the imaging of stretched single molecules with potential applications for single molecule sequence mapping. Lab-on-a-chip devices for single cell trapping and lyzing, genomic DNA extraction from single cells, and optical mapping of genomic length DNA has been demonstrated separately. Yet the pursuit for applying DNA optical mapping to solve real genomics challenges is still to come. We review lab-on-a-chip devices from literature that could be part of a complete system for the sequence mapping of single DNA molecules.

Keywords: DNA; lab-on-a-chip; microfluidics; nanofluidics.
