Dirty job made easier: Microfluidic technique recovers DNA for IDs

A team of researchers at the National Institute of Standards and Technology (NIST) and Applied Research Associates, Inc. (ARA, Alexandria, Va.) has demonstrated an improved microfluidic technique for recovering DNA from real-world, complex mixtures such as dirt. According to a recent paper, their technique delivers DNA from these crude samples with much less effort and in less time than conventional techniques. It yields DNA concentrations that are optimal for human identification procedures and can potentially be miniaturized for use outside the laboratory.
