By pulling DNA molecule through tiny, chemically activated hole in graphene and detecting changes in electrical current, researchers at NIST simulated new concept for rapid, accurate gene sequencing. NIST study, "Nucleobase-functionalized graphene nanoribbons for accurate high-speed DNA sequencing," suggests this method could identify ~66 billion bases/sec with 90% accuracy and 0 false positives. This might prove faster and cheaper than conventional DNA sequencing.
