Amyloid-mediated synthesis of giant, fluorescent, gold single crystals and their hybrid sandwiched composites driven by liquid crystalline interactions

► A novel method on the templating effect of β-lactoglobulin amyloid fibrils to synthesize giant gold single crystals. ► Green synthesis of the fluorescent gold microplates. ► Hybrid sandwiched gold single crystal composites. ► Nematic liquid crystals.
