It may also be possible to increase data accuracy by recapturing DNA molecules into the same nanopore244 or by using multilayer nanopores for multiple sequencing of each molecule. After removing the hairpin sequence, the template and complement reads, called the 1D reads, are used to generate a consensus sequence, called the 2D read, of higher accuracy. Obtaining megabase-scale or longer reads will require the development of HMW DNA extraction and size selection methods as well as protocols to maintain ultralong DNA fragments intact. Nat. Biol.
