Source data are provided as a Source Data file. a Coarse-grained simulation setup. b Diagram of charge distribution around DNA at 1 M NaCl from CG simulations. c Diagram of DNA overcharging from CG simulations with a DNA diameter of 2 nm and an ion diameter of 0.3 nm. d Electric potential, \({\Phi }_{{{{\rm{E}}}}}\), as a function of radial distance obtained from all-atom and CG MD simulations. e Phase diagram of DNA overcharging. The symbols represent experimental data from our work and a previous study12. Ions are modeled as hard spheres with different diameters, \({D}_{{{{\rm{i}}}}}\). f The overcharging electric potential for different ion diameters. g Maximum of \({\Phi }_{{{{\rm{E}}}}},\,{\Phi }_{{{{\rm{E}}}}}^{\max }\) versus \({c}_{{{{\rm{salt}}}}}\times {D}_{{{{\rm{i}}}}}^{2}\) for different ion diameters.
