Figure 2.

Graphs from DLS show the effect of the different parameters on LNP size and polydispersity index (PDI) 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), and (e) x₅ (antisolvent stirring speed, rpm). The precise particle size distribution from DLS is given in Figure S5. Results of the different parameters on LNPs zeta potential are given in Figure S7.
