Faster, Cheaper DNA Sequencing Method Devised

Boston University **biomedical engineers** have devised a method for making future **genome sequencing** faster and cheaper by dramatically reducing the amount of **DNA** required, thus eliminating the expensive, time-consuming and error-prone step of **DNA amplification**. The technique uses electrical fields to feed long strands of DNA through four-nanometer-wide pores, much like threading a needle. The method uses sensitive electrical current measurements to detect single DNA molecules as they pass through the nanopores.
