"occurs in butterfly wing scales functioning as photonic crystals to control visible light... complex gyroid structure self-assembled from designer colloidal particles of 100s of nm... patchy spheres with decorated surface encode target structure information... chirality, which is lacking in a diamond structure... bottom-up routes to colloidal gyroid structures pave the way for a new generation of experimentally achievable photonic crystals... lasers, sensors, and also devices for harvesting solar energy"
