In this work, we suggested the realization of supramolecular assembly of single walled carbon nanotubes (SWNTs) with the peptides for the directed growth and assembly of Au nanoparticles onto one-dimensional (1D) arrays. The programmed peptides containing phenylalanine and cystein groups can serve as bifunctions to create highly definable supramolecules of SWNTs and peptides and to guide the 1D arragement of Au NPs. We find that the highly stable dispersion and electrical properties of this conjugation were applied them into producing transparent conductive flexible thin films under vacuum filtration. As-obtained thin films were used as biosensing platforms for detecting biomolecules through electrochemical sensing method. The biosensor device shows a high sensitivity, low detection limit, and fast response time.
