(a) Different pH levels affected stiffness and viscous losses at different levels. (b) DNA bundles showed similar characteristics under different pH levels. Results of 3 different bundles were normalized according to their response at pH 4.1. (c) Increasing Ag+ concentration resulted in an increase in the stiffness. However, the viscous losses stayed constant even at higher Ag+ concentrations. (d) Results of 4 different bundles were normalized according to their response at 1 mM Ag+ concentration. All error bars correspond to standard deviations.
