A biomolecular-derived route for the self-assembly of inorganic nanoparticles using the recognition properties of antibodies attached to the surface of the gold nanoparticles is reported. The high specificity of antibody–antigen coupling is exploited to generate extended three-dimensional networks of metal nanoparticles (see Fig.) which can exhibit higher-order structures such as wires and filaments.
