The advent of electron microscopy and nanobiology has moved our appreciation of the living world to unprecedentedly small scales – with entirely new benefits and potential pitfalls to consider.
You’ll be amazed how much nanotechnology is found in the average house.
From the kitchen sink to the laundry and garage -- nanotechnology has already made its way into the average household.
Tastier salt, packaging that alerts you to food that has gone off and fish oil that tastes better – nanoparticles have lots of potential.
Some companies have used nano-titanium dioxide to make powdered sugar on donuts whiter.
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.
What’s in the bottle is good for me, right?
Microscopic needle-like particles don't seem like something you'd want to feed a baby. Whether safe or not, the way we deal with nanoscale food additives leaves plenty of other questions.
A single-atom engine is the latest example of how nano-technology can create machines to power tiny robots inside the body.
With reserves of indium tin oxide running low, what will replace it as the leader in transparent conducting materials?
Touch screens are everywhere these days but the materials commonly used to make them are not that abundant. So what are the alternatives?
A new method for creating a form of graphene with carbon dioxide sucked from the air has been announced with misleading claims.
Substances, such as these carbon nanotubes, can behave differently at the nano-scale, and may post a health risk.
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.
It’s dirty work… and that’s only the visible dust.
Tiny nanoparticles emitted during building work can enter your lungs and bloodstream.
Nanoparticles: small but deadly… to cancer.
New research could into nanoparticles could help deliver drugs straight to the site of tumours and make them more effective when they get there.
The picture is awesome… but am I risking my health?
Earlier this week, The Conversation reported that, “The future is bright, the future is … quantum dot televisions.” And judging by the buzz coming from this week’s annual Consumer Electronics Show (CES…
Drink without worry.
Recently the American publication Mother Jones published an article on the dangers of food laced with tiny metal oxide particles. The article, however, is laced with errors and misinformation. The source…
A world-first computer model that simulates cancer growth has been developed by an Australian PhD student. The device has…
Nanosafety research ensures everyday use of nanoparticles – such as sunscreen – stays safe.
Nanoparticles — or nanomaterials, as they are often called — are chemical objects with dimensions in the range of 1-100 nanometres (nm). Particles this tiny are hard to imagine, but it may help to think…
A new nanoparticle that can be taken orally has been developed, making injections of particles no longer necessary. Nanoparticles…
Tiny, but they make a big difference: nanoparticles build up in the environment in all kinds of ways.
Major advances in technology are being spawned by the synthesis and application of nanoparticles and nanocomposites. The nanotechnology revolution offers great promise for major advances in medicine, manufacturing…
Chemical engineers from the University of New South Wales have synthesised a new iron oxide nanoparticle that delivers cancer…
Scientists have merged tiny gold and iron oxide particles, then added antibodies to steer them through the bloodstream towards…
Cancer researchers are not shy of using nanotechnology. Their work is making promising headway into developing safer and more effective treatments. And now, new developments in the area mean that the general…
