Blood tests using nanoparticles carrying molecules which can detect breast cancer biomarkers could save millions of lives and open the way to mass screening for many cancers.
Prof. Matt Trau, of the Australian Institute for Bioengineering & Nanotechnology at the University of Queensland, and his team are using a combination of nanotechnology and molecular biology in the project, funded by a five-year $5 million grant from the National Breast Cancer Foundation.
Microscopic magnets ferrying drugs through the bloodstream directly to diseased tissue are a new ‘green chemistry’ product which will improve health and the environment.
A team led by Prof. Colin Raston, of the University of Western Australia fabricated the nano ‘bullets’ which can be directed by an external magnetic field to specific parts of the body. The new technology will enable doctors to send the drugs directly to the disease site, leaving healthy tissue intact and minimising toxic side-effects.
Two thousand years ago, Roman glass blowers used gold nanocrystals to create vases with brilliant colours ranging from red to purple. Today, gold nanocrystals are being used as catalysts in chemical reactions and may even become high-density data storage devices.
Gold nanocrystals aren’t gold in colour. They change colour as their size and shape change.
