Gold single‐crystal platelets with high aspect ratio are combined with amyloid fibrils to design a new class of hybrid nanocomposites. The films gather physical properties from both constituents, for example, plasmon resonance, fluorescence, and water‐dependent conductivities ranging from insulating to metallic levels, yet mirroring gold within a broad range of composition, and can serve multiple purposes such as sensors, diagnostic, printed electronics, micromechanical, and biological devices.
