TL;DR: The secondary structure of a 16 amino acid containing helical peptide has been compared to that on gold nanoparticles having increasing core diameter and the peptide changes primarily to the β-sheet conformation on 5 nm GNPs and gradually transforms into the native helical structure as the surface curvature is reduced by increasing the core size.

TL;DR: In this paper, three hydrophobic leucine-rich peptides Fc18L, Ac18L and 18LAc were prepared, equipped with a cystein sulfhydryl group which enables the formation of thin films on gold surfaces.

TL;DR: Electrochemical studies of a set of ferrocene-labeled helical peptides of increasing length were carried out by forming self-assembled monolayers (SAMs) on gold electrodes, and the rate of formation of the more conductive 310 conformer has been proposed to be related to the ET rates observed.

TL;DR: This study describes the electron transfer (ET) phenomenon through a series of (Pro-Hyp-Gly) repeat units containing collagen mimics containing redox-active ferrocene and thiol-functionalized cystein at the N- and C-terminals.

TL;DR: In this paper, the preparation of the new ferrocenoyl histidyl conjugates N- Fc-His-OMe (2) and N-Fc- His(o -N -Fc)-OMe(3) is reported together with their spectroscopic and electrochemical characterization.
