Using Ultrafast EMCCD Cameras for Faster DNA Sequencing

To decode the human genome and gain a greater understanding of diseases and their aetiology, advances need to be made in the rate at which the nucleotides that comprise DNA can be sequenced. Approaches to DNA sequencing have moved on considerably since the development of “chain-terminator” methods by Maxam and Gilbert, and by Sanger, in the1970s, and are now evolving beyond the so-called “next generation” toward today’s “third generation” systems.
