Forensic science experts at Flinders University are refining an innovative counter-terrorism technique that checks for environmental DNA in the dust on clothing, baggage, shoes or even a passport.

The Flinders-led research, led by postdoctoral research associate Dr Jennifer Young, will developed a system to trace the source of dust on suspect articles to match a soil profile of a specific area or overseas country.
“This could help provide evidence of where a person of interest might have travelled based on the environmental DNA signature from dust on their belongings,” said Dr Young from the College of Science and Engineering at Flinders University.
The project has received a state government Defence Innovation Partnership (DIP) grant of almost $150,000 to develop the intelligence and forensic potential of dust traces for counter-terrorism and national security, working with the Australian Federal Police and university partners (University of Adelaide and University of Canberra) to match the DNA extraction and amplification technique to Australian soil profiles from Geosciences Australia.
“This microscopic environmental trace evidence, based on soil geochemical, bacterial and fungal analysis would complement and enhance current forensic intelligence tools,” Dr Young stated in new research in Forensic Science International: Genetics.
Professor Adrian Linacre, chair in Forensic DNA Technology at Flinders, said environmental samples serve as ideal forms of contact trace evidence as detection at a scene can establish a link between a suspect, location and victim.
“Environment samples extracted via the ‘massively parallel sequencing’ technology provide biological signatures from complex DNA mixtures and trace amounts of low biomass samples,” he said.
The project is among more than $1 million in funding announced in the fourth round of the DIP’s Collaborative Research Fund.
InFoDust: The intelligence and forensic potential of dust traces for counter-terrorism and national security, led by Dr Young, will put the new technique on trial with soil reference data from across Australia provided by partner Geoscience Australia.
The new research paper, 'Massively parallel sequencing is unlocking the potential of environmental trace evidence (2021)' by Dr Young and Professor Linacre, is available online in the journal Forensic Science International: Genetics Volume 50, January 2021.
Flinders University is also a partner in another $150,000 DIP project to support Australia’s future defence capabilities. Flinders-based Voxon Photonics, Flinders University and other university experts will work with BAE Systems Australia and the Royal Australian Navy to adapt the Voxon technologies to develop superior battlespace visualisation.
“The exceptional scope of projects in this funding round demonstrate the breadth of innovation and real-world impact of South Australian researchers and industry,” says DIP Advisory Board chairman Kim Scott.
“Science and technology is identified in the Defence Strategic Update as a key enabler of the successful delivery and sustainment of the nation’s enhanced defence capabilities.”
