Yau, Shimmering wood - Experimenting with nanocellulose-based structural colour

Structural colour refers to the colouring that arises from the interaction of light with nanostructures. For example, the vivid, shiny, metallic-looking blue colour on the surface of morpho butterflies' wing is created when light interacts with nanostructures, resulting in the perception of colour by the human eye. Shiny and glittery colour effects are linked to structural colours; however, they are often produced using materials made from metals, plastics, minerals or their combinations. The...
