Abstract

An inverse opal structure was created using artificial melanin particles composed of a polystyrene core and a polydopamine shell as the template. The melanin-mimicking polydopamine that remained inside the inverse opal structure effectively absorbed multiple scattered light, producing bright structural color that was reversibly changed by solvent penetration.
