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 phenylalanine aromatic rings is derived and compared to a molecular model structure. These arrays have potential in future applications as functional nanoscale materials.
