Murdoch University researchers have developed a ‘green’ method to create antibacterial gold nanoparticles for potential use in the medical field with the help of common eucalyptus leaves.
Dr Gerrard Eddy Poinern, Director of the Murdoch Applied Nanotechnology Research Group (MANRG), said gold nanometre scale particles were on the leading-edge of health innovation.
“Gold nanoparticles have proven to be very versatile across a range of treatments, including in the delivery of double-stranded DNA in the emerging gene therapy area,” Dr Poinern said.
“They can also be passively accumulated in tumours for thermal treatment therapies, where they are heated to damage and kill cancer cells.
“And studies have shown that cancer drugs bonded to the surface of gold nanoparticles can effectively target tumours, improving delivery and minimising treatment durations and the side effects of anticancer drugs.”
Dr Poinern said, however, that up until recently, the particles’ production had involved expensive chemical and physical processes that often used toxic materials with potential hazards such as environmental toxicity, cytotoxicity and carcinogenicity.
