Australia’s place in the nanotechnology race

CSIRO researchers are applying nanotechnology to drug delivery, medical body imaging, nerve repair, smart textiles and clothing, medical devices, plastic solar cells (see From plastic money to plastic electricity) and much more.

“Nanotechnology is not an industry—it is an enabling technology,” says Clive Davenport, leader of CSIRO’s Future Manufacturing Flagship.

Supercomputer to test nanoparticles before we make them

Every new technology brings opportunities and threats. Nanotechnology is no exception. It has the potential to create new materials that will dramatically improve drug delivery, medical diagnostics, clean and efficient energy, computing and more. But nanoparticles could also have significant health and environmental impacts.

CSIRO physicist Dr Amanda Barnard is making the particles in the virtual world and testing how they interact in various environments before they get made in the real world.

Measuring mercury with a Midas touch

RMIT University researchers have used nanotechnology to create a pioneering sensor that can precisely measure one of the world’s most poisonous substances—mercury.

The mercury sensor developed by RMIT’s Industrial Chemistry Group uses tiny flecks of gold that are nano-engineered to make them irresistible to mercury molecules.

From Roman nanocrystals to new gold catalysts

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.

A team led by Prof. Paul Mulvaney, at the University of Melbourne, is using gold nanocrystals as a colour-coded catalyst.

From plastic money to plastic electricity

Tomorrow’s solar panels could bear an uncanny likeness to Australia’s polymer banknotes.

In fact, the first prototypes of a new kind of solar panel are being printed on the same printing presses that print Australia’s money.

The research team are confident that within five years these plastic solar panels will start appearing on windows, shade clothes and roofs across Australia.
