Automated bead-trapping apparatus and control system for single-molecule DNA sequencing.


We have been investigating a microfluidics platform for high-speed, low-cost sequencing of single DNA molecules using novel "charge-switch" nucleotides. A significant challenge is the design of a flowcell suitable for manipulating bead-DNA complexes and sorting labeled polyphosphate molecules by charge. The flowcell is part of a single-molecule detection… (More)
