A more in-depth description on the new way to sequence DNA.
The brilliant minds at Harvard tell us that they use graphene to help sequence.
Scientists drill a nanopore into a graphene membrane, then pass a strand of DNA through it. When the DNA is passed through it, and measure the exchange of ions. Why graphene? It also conducts electricity. The exchange of ions affects the graphene's electrical conductivity. The conductivity is then measured and the change in conductivity would tell us the chemical.
Still, the problem remains that the speed that the DNA is passed through the nanopore. Once this is controlled, DNA will be cheap and easy.
