Figure 13: Plot of hydrodynamic size and zeta potential of DNA-GB intermolecular complexes without and with 0.05% [C8mim][Cl] solutions at pHc where associative interactions ensue and soluble complexes are formed. Charge reversal and overcharging is clearly seen in Region-III. All measurements were performed at room temperature 20°C. Here, DNA concentration was fixed at 0.05%. Dotted line defines complete charge neutrality. Solid lines are guide to the eye. [95] - Reproduced by permission of the PCCP Owner Societies.
