“…In agreement with the I-C data and theoretical model presented above, the pore conductance overproportionally increases with increasing electrolyte concentration at low concentrations. Our results are in close agreement with the data reported by other researchers fabricating cylindrical and conical nanopores in surface charged membranes [28,29].…”

“…Applied voltages range from +10 mV to +100 mV. Although standard electrolyte concentrations for biological experiments only range down to 0.1 M, we have still measured the current through our nano pore for the two additional electrolyte concentrations of 0.02 and 0.5 M. In accordance to the previous studies [29], we also identified that the dependence of the ionic current through a single artificial nano pore on the electrolyte concentrations deviates to a curve with a steeper slope at all the voltages applied as the electrolyte concentration is lowered to values below 0.1 M (Figure 4).…”

“…Various groups have started to use single conical pores with very small diameters (Siwy et al, 2003(Siwy et al, , 2002 as sensors for single molecules, e.g. desoxyribonucleic acid (DNA) (Heins et al, 2005;Mara et al, 2004;Schiedt et al, 2005).…”
