RT Journal Article T1 1D alignment of proteins and other nanoparticles by using reversible covalent bonds on cyclic peptide nanotubes A1 Priegue Caamaño, Juan Manuel A1 Louzao Pernas, Iria A1 Gallego Gómez, Iván A1 Montenegro García, Javier A1 Granja Guillán, Juan Ramón AB Self-assembling cyclic peptide nanotubes are supramolecular structures whose diameter and external surface properties are precisely controlled. In this communication we describe a general strategy to align different molecules on top of the nanotube surface by using cyclic peptides bearing chemoreversible reactive groups. D,L-α-Cyclic peptides endowed with a hydrazide moiety were condensed with a pyrenecarboxyaldehyde to facilitate the nanotube formation and deposition on flat unfunctionalized surfaces. The hydrazide moieties can be liberated without affecting the tubular structure and then used to align on top of the nanotube other molecules bearing aldehyde functions. Additionally, the attachment of specific ligands allowed the supramolecular alignment of corresponding receptors, such as mannosyl aldehyde and concavaline-A, driven by the nanotube structure through complemetary protein–ligand interactions PB Royal Society of Chemistry SN 2052-4110 YR 2021 FD 2021 LK http://hdl.handle.net/10347/29370 UL http://hdl.handle.net/10347/29370 LA eng NO Org.
