The use of biomolecules to synthesize inorganic nanomaterials, including metallic nanoparticles, offers the ability to induce controlled growth under mild environmental conditions. Here, recently discovered silk-like "suckerin" proteins are used to induce the formation of gold nanoparticles (AuNPs). Advantage is taken of the distinctive biological and physico-chemical characteristics of suckerins, namely their facile recombinant expression, their solubility in aqueous solutions, and their modular primary structure with high molar content of redox-active tyrosine (Tyr) residues to induce the formation of AuNPs not only in solution, but also from nanostructured solid substrates fabricated from suckerins.
