In article number 2002471, Antonio Tricoli and co‐workers use the scale‐invariant features of fractals obtained by Brownian motion for the realization of a tunable family of photonic metamaterials consisting of a 3D distribution of plasmonic and semiconductor nanoparticles. The short‐ and long‐range periodicity of these fractal metamaterials enables advanced light–matter–fluid interaction and, when used for optical sensing of volatile molecules, they demonstrate an outstanding room‐temperature sensitivity.
