Figure 17: Plot of hydrodynamic size and zeta potential of DNA-GA intermolecular complexes without and with 0.05% [C8mim][Cl] solutions at pHc where associative interactions ensue and soluble complexes are formed. Here, DNA concentration was fixed at 0.005%. Note the DNA chain softening due to binding with GA in Region-I. Charge reversal and overcharging is clearly seen in Region-III. Dotted line defines complete charge neutrality. Solid lines are guide to the eye. [95] - Reproduced by permission of the PCCP Owner Societies.
