research Structural Color of Partially Deacetylated Chitin Nanowhisker Film Inspired by Jewel Beetle
In this study, researchers created nanowhiskers from crab shell-derived nanochitin that self-assembled into vibrant structural colors within a film. The material, sensitive to environmental changes, shows potential as a food freshness indicator and a sustainable dye for cosmetics due to chitin's biocompatibility.
