South Korean volunteer workers clean up an oil spill in December 2007. Could such scenes soon be a thing of the past? AAP

Don’t cry over spilled oil – use nanosheets

We’re all too familiar with footage of ruptured tankers or busted rigs dumping millions of litres of oil into the sea, coating shorelines and animals in crude sludge. Many traditional methods of cleaning…
It’s the sun rather than nanoparticles in sunscreen that poses the real health risk. Edson Soares

Time to dispel the fear of nanoparticles in sunscreens

The sunny season has well and truly started, as has the daily summer ritual of applying sunscreen. So now is the perfect time to consider whether “nano sunscreens”, which contain UV filtering nanoparticles…

Power to you: carbon nanotube muscles are going strong

Just on a year ago my colleagues and I announced our discovery that carbon nanotube yarns could be made to twist and rotate at great speeds when electrically stimulated. In this way we had created “artificial…

When nanoparticles (almost) touch

When two gold nanoparticle spheres are pushed sufficiently close together, the gap between them acquires a red colour, as…

Blue for yes, red for no: detecting HIV instantly

A new, cheaper test that diagnoses cancer or HIV in an instant could help tackle disease early in developing countries, UK researchers have said. Researchers from Imperial College London have developed…

MOF the chart: why a record-breaking surface area matters

You may not immediately think of world records when you consider chemistry, but that’s exactly what some chemists are thinking about during their research. Many, working on something called metal-organic…

The tiny world of acid-powered rockets

A new acid-powered micro-rocket could be used to deliver drugs within the human body. The micro-rocket works by converting…
