Project could deliver DNA testing at the crime scene
A research project examining new methods of speeding up DNA profiling could lead to the results of tests on samples being known in less than half an hour preventing crime suspects being released before DNA profiles have been confirmed.
A research project examining new methods of speeding up DNA profiling could lead to the results of tests on samples being known in less than half an hour preventing crime suspects being released before DNA profiles have been confirmed.
The £50,000 project, being carried out by the University of Southampton in partnership with LGC, will focus on developing new techniques to identify the length of DNA strands the key indicator to each individuals DNA fingerprint.
Current testing methods require DNA extraction, amplification, and lengthy gel-based separation and analysis; its a process which usually takes at least a day, and because of the equipment needed is confined to specialist analytical laboratories.
As a result, suspects may be released and later found to be associated with a serious crime, re-offend or disappear; substantial costs can also be incurred in trying to re-arrest those suspects.
Using new technology developed by LGC, the research project funded by the Engineering and Physical Sciences Research Councils Think Crime Programme could potentially deliver DNA test results to the same accuracy within 15-30 minutes.
The research could lead to DNA testing being carried out at crime scenes or police stations, in much the same way the introduction of LiveScan has led to the rapid analysis of fingerprints.
The 12-month research project began on November 1, 2005, and is being carried out by a team led by Southampton University chemist, Professor Tom Brown; details of the feasibility study appeared in the recent edition of New Scientist magazine.
