Scientists at Ion Torrent Systems Inc. have created a DNA sequencing technique using semiconductors instead of the costly and complex optical technology. They say their device has a much lower cost, it is portable and can be upgraded (scalable). Their aim is to achieve the target price of $1,000 for a genome sequencing. Company founder, Dr. Jonathan Rothberg, the machine's inventor, and team wrote in the journal Nature this week: "The seminal importance of DNA sequencing to the life sciences, biotechnology and medicine has driven the search for more scalable and lower-cost solutions...
