Self-assembled diphenylalanine (FF) peptide nanotubes (PNTs) have attracted significant attention due to their well-ordered supramolecular structure and wide range of functional capabilities that may enable potential nanobiotechnology applications. However, self-assembled PNTs are generally inhomogeneous at the macroscale, which has limited their potential use. Reproducibly controlling the assembly and alignment of PNTs is therefore critical to enable the widespread use of PNTs, e.g., in optical sensing of biomolecules or energy harvesting applications. Templates formed from aligned FF-PNTs with plasmon-active metal nanoparticles or graphene oxide are a promising nanocomposite for large-scale, rapid, stable, sensitive, biocompatible, and cost-effective surface-enhanced Raman scattering (SERS) substrates.
