Abstract:

 

The sensing of individual molecules as they pass through nanopores under an   external field is a popular research field. The approach is simply based on   the detectable temporary blockades in the ionic current as the molecules   pass through the nanopores. These signatures of the current have been shown   to be a function of nanoparticle and nanopore size and geometry as well as   the external electric field. However, models developed in this context fail   to predict the experimentally observed behavior in technologically important   shorter nanopores. Here we present atomistic molecular dynamics simulation   results from colloidal nanoparticle translocation through mid-to-low aspect   ratio charged nanopores under an external field. We show that not only the   pore length but also the ion concentration of the media and the nanoparticle   charge have important effects on the ionic current.
