Researchers create novel nanotechnique to sequence human genome

Since the human genome was sequenced six years ago, the cost of producing a high-quality genome sequence has dropped precipitously. More recently, the National Institutes of Health called for cutting the cost to $1,000 or less, which may enable sequencing as part of routine medical care. Physicists at Brown University may have an answer. They introduce a novel procedure to vastly slow the DNA's movement through openings that are used to read the code. In the journal **Nanotechnology**, the physicists report the first experiment to **move DNA through a solid-state nanopore using magnets**. The approach is promising because it allows multiple segments of a DNA strand to be threaded simultaneously through numerous tiny pores and for each fragment to move slowly enough through the opening so that the base pairs can be accurately read.
