Kinetics of 1D-rod formation. a Optical spectral changes upon the addition of Ni2+ to K44Z at 22 °C. Inset: Time-dependent absorbance at 280 and 312 nm. b Elution trace of K44Z incubated with Ni2+ (3 equiv.) at 22 °C for 0–24 h from S200 column. The sequential order of the reactions was labeled. c Time-dependent rod-growth with K44Z (5 μM) at 37 °C monitored by TEM. d A proposed scheme for 1D assembly. The raw data in Fig. 4a, c are provided as a Source Data file.
