Figure 14: Plot of solution turbidity measured at 450 nm as function of [C8mim][Cl] concentration at pHc. Maximum associative interaction was noticed at 0.05% IL concentration. DNA concentration was maintained at 0.005% for GA and 0.05% for others polyions. Polyion concentrations were fixed at 0.1% for GA, GB and GB. In case of chitosan, it was fixed at 0.05%. All measurements were performed at room temperature 20°C. Region-I is characterized by formation of soluble complexes that are precursors to liquidliquid phase separation and in Region-II these complexes coalesce to form large in soluble complexes.
