DNA sequencing revolution?

This press releass via Eurekalert:

Nanopore method could revolutionize genome sequencing

"A team led by physicists at the University of California, San Diego has shown the feasibility of a fast, inexpensive technique to sequence DNA as it passes through tiny pores. The advance brings personalized, genome-based medicine closer to reality.

The paper, published in the April issue of the journal Nano Letters, describes a method to sequence a human genome in a matter of hours at a potentially low cost, by measuring the electrical perturbations generated by a single strand of DNA as it passes through a pore more than a thousand times smaller than the diameter of a human hair. Because sequencing a person's genome would take several months and millions of dollars with current DNA sequencing technology, the researchers say that the new method has the potential to usher in a revolution in medicine."

This is really interesting research, lets hope it can be implemented effectively and cheap genomes become a reality.

Do you like playing in the game which you need to use maple mesos, when you do not have mesos, you must borrow cheap mesos from friends, or you buy maplestory mesos. If you get maple story mesos, you can continue this game.
