Isolated metallic arrays of spherical cavities (see Figure) have been prepared using a simple scheme that combines two self‐assembly steps using monodisperse polystyrene spheres of two different sizes and electrochemical deposition. The ability to easily fabricate, at low cost, a large variety of such photonic metallic structures promises applicability in many diverse areas, ranging from biotechnology to optoelectronics.
