Rapid Polymer Sequencer

Solid-state, nanopore-based analysis of nucleic acid polymers is the only technique that can determine information content in single molecules of genetic material at the speed of 1 subunit per microsecond. Because individual molecules are counted, the output is intrinsically quantitative. The nanopore approach is more...
