“…Since it is difficult to replicate the patterning process and the structural colours, such systems can find a market value where iridescent, non-fading structural colours are favourable, such as printing on banknotes, passports, and certificates. 224 The colorimetric response of structurally coloured systems to temperature changes, [225][226][227] as well as the colour changes against chemical interactions in the gas phase or through liquid solvent interactions (such as solvent vapour infiltration, 131,228,229 ionic media and pH changes, 230,231 and interaction with special molecules 232 ) can be used in various sensing applications (see Fig. 11B, for example).…”

Nature has mastered the construction of nanostructures with well-defined macroscopic effects and purposes. Structural colouration is a visible consequence of the particular patterning of a reflecting surface with regular structures at submicron length scales. Structural colours usually appear bright, shiny, iridescent or with a metallic look, as a result of physical processes such as diffraction, interference, or scattering with a typically small dissipative loss. These features have recently attracted much research effort in materials science, chemistry, engineering and physics, in order to understand and produce structural colours. In these early stages of photonics, researchers facing an infinite array of possible colour-producing structures are heavily inspired by the elaborate architectures they find in nature. We review here the recent technological strategies employed to artificially mimic the structural colours found in nature, as well as some of their current and potential applications.
