| Typical images showing the conformations of DNA–spermidine complexes in different solutions with varying salt concentrations. Panels (a1)–(a5) correspond to the NaCl solution, and panels (b1)–(b5) are in the MgCl2 solution. From left to right, the concentrations increase from 0 to 1 M. (c) The mean diameter 〈 D 〉 of DNA condensates as a function of salt concentrations in NaCl and MgCl2 solutions. |
