Formation of K44Z-rods. a TEM and b AFM images of K44Z (10 μM) incubated with Ni2+ (3 equiv.) for 24 h at 22 °C. c The length in Fig. 2a (black) and after optimization (red); K44Z (50 μM) and 8 equiv. Ni2+ (8 equiv.) at 37 °C. The average lengths (Ln) were determined by measuring 315 (PDI = 2.08) and 258 (PDI = 1.89) rods formed at the initial condition and after optimization, respectively. The raw data in Fig. 2c are provided as a Source Data file.
