Studying the Current Modulation of Bundled DNA Nanostructures in Nanopores

Experimental studies on the current modulation of bundled DNA structures revealed a non-monotonic dependency between the salt concentration of vanishing modulation and the size of the DNA bundle. Noteworthy, this crossover salt concentrations significantly deviate from the concentration for a single DNA molecule. We present results for simulation models on different levels of detail that show consistent results but deviate from the experimental findings.
