A single-atom engine is the latest example of how nano-technology can create machines to power tiny robots inside the body.
Vantablack is the darkest pigment ever – thanks to carbon nanotubes.
Two very similar new carbon nanotube products, released eight years apart, provoked very different reactions. What's changed about the way we consider nanotechnology risks and benefits?
Hidden tools are making the world a safer place.
From tiny robotic doctors repairing your body to the latest climate change-tackling tools, nanotechnology is fighting an invisible battle on our behalf.

Quantum dots - minuscule semiconductor particles with specific light-absorption properties - can kill drug-resistant superbugs without harming the surrounding healthy tissue.
Chemistry is all around us.
Our civilisation is built on chemistry, and the science has a bright future, with the launch of a new Decadal Plan that will steer the science into the future.
Titanium ore can be used to develop lithium ion batteries and supercapacitors, which can aid South Africa’s energy problems.
South Africa his rich in minerals that, combined with the development of nanotechnology, can be used to help it develop new energy technologies.
Nanotechnology that can detect illnesses will become available next year.
A novel approach to detect bacterial infections in 10-15 minutes is expected to become commercially available next year.
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.
Fluorescent security ink produces multicolor barcode visible under UV light.
Invisible under normal light but fluorescent under UV light, this ink can print out unique signatures that use 'molecular encryption' to authenticate anything they tag.
Graphene powder can be manufactured.

There is much excitement about graphene, a material only a single carbon-atom thick, but finding ways to do something with it that's affordable have always been a challenge.
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.
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.
Fossil fuels can only go so far towards meeting our burgeoning energy demands.
A non-metal alternative to platinum electrodes in fuel cells could make them an affordable solution for energy security.
With emerging technology comes great responsibility.

The World Economic Forum's new list of the Top Ten emerging technologies reminds us that the promise of innovation comes with responsibilities.
Future technology won’t just be a gadget we use, it will re-structure our societies.
Throughout history, whenever new technologies have emerged that change our means of production and ability to communicate they have tended to transform society. The rapid technological development of the…
Ok, that’s not the way to extract it.
In the development of new drugs, taking something from nature and modifying it has been a successful tactic employed by medicinal chemists for years. Now, with the help of nanotechnology, researchers are…

Don’t be mesmerised by cool apps and flashy new gizmos – the top technology inventions of the year are ones that will have a lasting effect. Most are advances in fields that are already changing us. Some…
Plants use photosynthesis to build molecules and energy they can use. By copying plants, humans can make cleaner fuels.
Most of the energy that fuels our lives comes from plants. Whether it is a fossil fuel that was formed hundreds of millions of years ago or the food we eat, all carbon-borne energy has its ultimate origins…
The last resort.
Development of new drugs for treatment of disease is an expensive, time-consuming and labour-intensive effort for both pharmaceutical companies and academics. For the past 15 years, “cost per approval…
They have cancer in their sights.
It sounds like a scene from a science fiction novel – an army of tiny weaponised robots travelling around a human body, hunting down malignant tumours and destroying them from within. But research in Nature…
US researchers have invented a microchip-based test for type 1 diabetes. The test is carried out by a handheld microchip…
