Electronically sequencing single contiguous strands of DNA may no longer be fantasy. With the technique under consideration by Daniel Branton and Jene Golovchenko, an entire human genome could be sequenced in hours.
``A revolutionary technology for probing, and eventually sequencing, individual DNA molecules using single-channel recording techniques has been conceived. This technology is based on a very high speed method that: 1) Translates the characteristics of a polynucleotide into electronic signals; 2) Has the potential to sequence DNA at unprecedented speeds; 3) Can probe very long stretches of DNA or RNA; 4) Is a high throughput, single molecule technique compatible with high levels of nanofabrication.''
