Illustration of the Tyndall effect, a light-scattering phenomenon, in flasks containing increasing concentrations of zirconia nanoparticles, lit up by a laser pointer. The first flask only contains water, so the laser beam is not scattered and remains invisible. In the flasks after that, the higher the concentration of nanoparticles, the more the beam is scattered by the medium. This experiment can be used to check whether nanoparticles have been successfully synthesised.

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
