Alignment of Aromatic Peptide Tubes in Strong Magnetic Fields

Diphenylalanine (FF) peptides self‐assemble into well ordered, discrete, hollow nanotubular structures under relatively simple conditions. AFM is used to investigate alignment of FF tubes in strong magnetic fields. Using the direction of alignment, a constraint on the orientation of the phenylalanin...

Description
Summary:Diphenylalanine (FF) peptides self‐assemble into well ordered, discrete, hollow nanotubular structures under relatively simple conditions. AFM is used to investigate alignment of FF tubes in strong magnetic fields. Using the direction of alignment, a constraint on the orientation of the phenylalanine aromatic rings is derived and compared to a molecular model structure. These arrays have potential in future applications as functional nanoscale materials.
