The use of a living fungus to ‘actively' assemble presynthesized gold nanoparticles over its hyphae, resulting in conducting microstructures (see figure), is reported. This physiologically (nutrition) driven process of colloidal self‐organization avoids the need for sophisticated DNA/protein chemistry for facilitating interfacing with biological surfaces. The obtained gold‐laden microstructures can be modified into flat ribbonlike or tubular morphologies by simple post‐formation processing.
