No big deal: there is little to fear from nanoparticles in food

Two new studies from Food Standards Australia and New Zealand show there's no evidence that nanoparticles in food present a health risk, but there's more research to be done.

How nanotechnology can help us grow more food using less energy and water

Growing enough food to feed 9 billion people by 2050 will require huge amounts of energy and water. Using nanoparticles to boost plant growth and yield could save resources and reduce water pollution.

Fighting superbugs with nanotechnology and light

Quantum dots - minuscule semiconductor particles with specific light-absorption properties - can kill drug-resistant superbugs without harming the surrounding healthy tissue.

Big questions about risk assessment of nanomaterials

We need to carefully assess nanomaterials to ensure their safety, but there are questions over whether the existing practice of risk assessment is up to the task.
New innovations and technologies, such as the Nanopatch developed by Australian biotech Vaxxas, are instrumental to Australia’s future prosperity, and many benefit from NCRIS facilities, which are now under threat from government cuts. AIBN

Intergenerational prosperity depends on supporting research

The government believes innovation will be crucial to our future productivity, yet it is threatening cuts to research infrastructure that is instrumental to promoting innovation and new technologies.
