That’s gold! Griffith finds cheap way to detect cancer

Griffith University scientists have developed a new class of nanomaterials that could detect early cancer.
The inexpensive, non-invasive diagnostic tool can deliver sensitive and specific results that are easily and quickly interpreted with less reliance on laboratory equipment.
Working with the team from the University of Wollongong (UOW), the researchers have developed a new class of enzyme-like nanovehicles using gold-loaded nanoporous iron oxide nanocubes for sensing body fluid which, despite containing gold nanoparticles, are inexpensive to make.
The researchers will keep refining the technology with the aim of developing a portable diagnostic device for less than $5.
Early diagnosis of cancer leads to more effective and cheaper treatment, and the majority of cancers can be treated successfully if they are detected at their earliest stages.
However, most current diagnostic methods use expensive biomaterials and rely on sophisticated instrumentation, limiting their use in developing countries and other resource-poor settings.
The team’s two-step diagnostic method uses the gold-loaded
