Figure 2: FF and CycloFF nanotubes growth rates.
From: Dynamic microfluidic control of supramolecular peptide self-assembly
(a) Crystalline conformation of a cycloFF monomer. (b) Elongation and shortening of preformed cycloFF nanotubes. At its critical concentration, the nanotube showed no change in length (5 min interval between images). Dissociation and elongation of the nanotube were demonstrated at subcritical (4 min interval between images) and supercritical (30 min interval between images) concentrations (1.70 and 13.59 mM), respectively. (c) FF nanotube growth rate displays a linear behaviour with increasing peptide concentration. (d) CycloFF nanotube growth rate as a function of increasing peptide concentration and best fit to the linear relationship R=kon × c−koff. Each data point represents the average growth rates of ten individual nanotube termini. Scale bar, 10 μm. Error bars represent the standard error of the growth rate of 10 individual tubes.
