SAXS and WAXS data for Figure 3B, where combined SAXS and WAXS patterns are presented for pure Cu-Asp as reference (prepared in water) and OCNF dispersions containing L-Asp at the following concentrations: a) 0 mM (control sample), b) 50 mM, c) 75 mM, d) 100 mM and e) 125 mM. C) SEM image of the cross section of an air-dried hydrogel showing bundles of Cu-Asp crystallites.
