Various structures derived from 1D rods and/or 2D planes. a Formation of hybrid structures upon the addition of K337Z (2 μM) and 3 equiv. of Ni2+ to the pre-formed K44Z-derived rods (10 μM) and 3 equiv. Ni2+ at 22 °C for 4 h. TEM images were obtained after 20 h incubation at 22 °C. b Addition of uranyl acetate (0.2 wt%) to the K44Z-derived rods. c Addition of polar organic solvents such as methanol and acetone to the optimized E13Z/K44E-derived rods (fourfold v/v).
