Figure 3.
Photographs from the TEM show the effect of the different parameters on LNP morphology with (a) x1 (initial lignin concentration, g/L), (b) x2 (solvent flow rate, ml/min), (c) x3 (antisolvent composition, water/EtOH, v/v), (d) x4 (antisolvent ratio, solvent/antisolvent, v/v), (e), and x5 (antisolvent stirring speed, rpm). Precise parameters are given above the photographs. Scale bars for all photographs: 200 nm. Additional images for x2 and x4 are available in the Supplementary Materials.
