Ultra-fast DNA sequencing

[wolfhnd]

BOSTON (5-19-10) -- Sequencing DNA could get a lot faster and cheaper – and thus closer to routine use in clinical diagnostics – thanks to a new method developed by a research team based at Boston University. The team has demonstrated the first use of solid state nanopores — tiny holes in silicon chips that detect DNA molecules as they pass through the pore — to read the identity of the four nucleotides that encode each DNA molecule. In addition, the researchers have shown the viability of a novel, more efficient method to detect single DNA molecules in nanopores.
