Schematic presentation for formation of electrical double layer and bulk flow of electrolyte (A) inside the nanopore (B) large pore diameters (65 nm) has space for bulk flow of electrolyte but as pore diameter decreases (C) and (D) the density of ions increases inside nanopores (E) Nyquist plot between the three different pore diameters 25 nm, 45 nm and 65 nm of NPA at constant length 4.5 μm and concentration (1 μM) of electrolyte NaCl shows the decrease in pore resistance R_p with increased pore diameter; (F) increase in electric conductance (G_p) with respect to pore diameter.
