KU Leuven researcher Ventsislav Valev and an international team of colleagues have developed a new method for manipulating light at the nanoscale in order to optically detect single molecules. By shining circularly polarised light on a gold, square-ring shaped nanostructure, the researchers were able to 'activate' the entire surface of the nanostructure, thereby significantly increasing the opportunity for interaction with molecules.

The sun breaks through the clouds - and surfaces start cleaning themselves! It may sound like magic, but in fact it's all thanks to the addition of titanium dioxide molecules. Activated by UV light, they trigger a reaction which destroys bacteria, algae and fungi, keeping items such as the armrests of garden chairs nice and clean.
