GeneWorks develops DNA barcoding tech

South Australian biotech GeneWorks has developed a new DNA barcoding technology for use as a security and authentication tool.

The technology has been designed for applications including anti-counterfeiting efforts, by invisibly marking protected items such as banknotes or artwork.

The markers use a combination of different-length DNA molecules, which are then mixed into a combination unique to that item.

The technology can also be formulated into a spray that can be used to uniquely tag intruders to a protected premise, linking them to the crime scene.

GeneWorks business development manager Rob King said that unlike existing DNA barcoding technologies on the market, his company's method is compatible with existing analysis techniques employed by forensic laboratories.

“Compatibility with forensic instrumentation and DNA databases means that this technology can be used as evidence for criminal convictions in court,” he said.

“Applications of the technology are endless and are especially useful in industries such as apparel and pharmaceuticals where companies suffer loss of revenue and reputation damage due to counterfeiting.”

Development of the barcoding technology was funded by the South Australian government, through BioSA. The technology will now be validated by Forensic Science SA, before production is scaled up to meet anticipated commercial demand.

GeneWorks' core business is the supply of molecular biology research products, particularly custom oligonucleotides and the provision of genome analysis services. The company was founded in Adelaide in 1996.
