Nanoparticles and nanosafety: the big picture

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…
Tiny, but they make a big difference: nanoparticles build up in the environment in all kinds of ways. Tiny, but they make a big difference: nanoparticles build up in the environment in all kinds of ways. victorpuntes/Flickr

Manufactured nanomaterials are a big deal in the environment

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…

Explainer: nanoparticles in air pollution

Hearing the words “airborne nanoparticles” for the first time, one would probably ask: just how tiny are they, where do they come from, and do we need to worry about them? These tiny particles between…
It’s the sun rather than nanoparticles in sunscreen that poses the real health risk. 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…

When nanoparticles (almost) touch

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