A few days ago I reviewed in brief the history of Helicos Biosciences (HCLS), a company that held out the promise of single molecule sequencing, but failed to deliver on several fronts to the next-generation sequencing market. (This would include accuracy, throughput per dollar, and ease of use / reliability was yet another factor.)
But why is single molecule sequencing so attractive in the first place? What can it do that other technologies cannot?
