Unveiling the secret of the stingray's electric blue

Description

City University of Hong Kong (CityUHK) researchers have uncovered a unique mechanism for producing the brilliant blue skin of ribbontail stingrays. This discovery sheds light on how nature can create vibrant colors through the particular arrangements of nanostructures, a process known as structural coloration. This research delves into the fascinating world of natural optics, revealing a novel approach to color production that could inspire new technologies for creating robust, chemistry-free colors on a variety of materials.
