| Özet |
| Nanopores as resistive pulse sensors can effectively detect single‐particles of several types including molecules without the need of labelling. Although pore geometry has a significant role in the formation of the obtained signals, it has been investigated relatively little. In the present study, we run simulations to consider the effects of pore geometry and compare conical, cigar and hourglass shaped pores at the conditions where both the resistive and conductive pulses occur in the conical pore. We examine the pulse magnitudes in relation to variations in size and charge for spherical particles. We also compare the pore geometries for when the particles pass through an off‐axis trajectory, close to the pore wall. The results show that distorting the conical shape into an hourglass or a cigar shape can significantly enhance the sensing capability of the nanopore. We show that at identical conditions, the hourglass pore … |
