From: Modulation of Peptide Based Nano-Assemblies with Electric and Magnetic Fields

Scanning electron micrographs of FF self-assemblies formed post annealing at room temperature conditions: The nanorods and nanotubes formed after five experimental conditions reported (0 V cm−1, 150 V cm−1 DC and AC electric field; 300 Vcm−1 AC and DC electric field) are shown. Field induced assemblies have greater tendencies of alignment and a morphological shift to rod like structures (compared to tubes) in the overall population of nano-micro dimensional structures.
