Nanoporous gold is a sponge-like material obtained by dealloying process with ligaments dimensions down to 10 nm range. The large surface to volume ration of this metamaterial gives possibility to strongly alter its optical properties by surface functionalization, so called chemical interface damping. We show that reversible surface oxidation of nanoporous gold can be used to switch its color.
