A surface displays structural colors when light is reflected by tiny, regular structural elements in a transparent material. Researchers have now developed a method to make structural colors from cellulose-based polymers by using coated droplets that exist in a surrounding fluid -- so-called liquid marbles. The system readily responds to environmental changes, which makes it interesting for applications in bio-based sensors and soft photonic elements, according to a new study.
