“Exploiting the fact that a hydrogen ion is released whenever a nucleotide attaches to a strand of DNA, sensors in Ion Torrent’s microchip have been designed to detect this chemical signature. “
“ they’ve (Oxford Nanopores) embedded a protein pore into a synthetic polymer membrane. The strand of DNA being sequenced is then passed through the pore and as each nucleotide goes through, it registers as a different electrical signal detected by Oxford’s machine.”
“Complete Genomics expects to churn out the complete sequences of 100,000 to 1 million genomes in the near future as they ramp up operations!”
