Abstract

Biomolecular templates provide an excellent potential tool for bottom-up device fabrication. Self-assembling α-synuclein protein fibrils, the formation of which has been linked to Parkinson's disease, have yet to be explored for potential device fabrication. In this paper, α-synuclein fibrils were used as a template for palladium (Pd), gold (Au) and copper (Cu) nanoparticle chains synthesis. Deposition over a range of conditions resulted in metal-coated fibers with reproducible average diameters between 50 and 200 nm. Active elemental palladium deposited on the protein fibrils is used as a catalyst for the electroless deposition of Au and Cu. Nanoparticle chains were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray energy dispersive spectrometry (XEDS), and electron energy loss spectrometry (EELS).
