Thanks for posting this. I wonder if they ever come up with a sequencing platform that relies on millions of nano machines crawling along the dna, sending signals of which nucleotide they just traversed.
well, there are many different approaches right now. I really gotta say, some of the stuff they came up with are ingenious. I'll try to introduce others if there is enough interest here =D.
Actually, most sequencing platforms work something like this. The "nano machine" is a natural or modified polymerase. Pacific Biosciences' new platform, supposedly commercially available in a year or two, matches your conception pretty closely.
