Graphene may hold key to speeding up DNA sequencing (9/14/2010)

Researchers from Harvard University and MIT have demonstrated that graphene can act as an artificial membrane separating two liquid reservoirs. By drilling a tiny pore just a few-nanometers in diameter, called a nanopore, in the graphene membrane, they were able to measure exchange of ions through the pore and demonstrated that a long DNA molecule can be pulled through the graphene nanopore just as a thread is pulled through the eye of a needle. ...> Full Article

Kinked nanopores slow DNA passage for easier sequencing (8/5/2010)

In an innovation critical to improved DNA sequencing, a markedly slower transmission of DNA through nanopores has been achieved by a team led by Sandia National Laboratories researchers. ...> Full Article

Researchers capture first images of sub-nano pore structures (6/10/2010)

Moore's law marches on: In the quest for faster and cheaper computers, scientists have imaged pore structures in insulation material at sub-nanometer scale for the first time. Understanding these structures could substantially enhance computer performance and power usage of integrated circuits, say Semiconductor Research Corp. (SRC) and Cornell University scientists. ...> Full Article

Lollipops and ice fishing: Molecular rulers used to probe nanopores (5/3/2010)

Using a pair of exotic techniques including a molecular-scale version of ice fishing, a team at the National Institute of Standards and Technology has developed methods to measure accurately the length of "nanopores," the miniscule channels found in cell membranes. The team's "molecular rulers" could serve as a way to calibrate tailor-made nanopores -- whose diameters are nearly 10,000 times smaller than that of a human hair -- for applications such as rapid DNA analysis. ...> Full Article
