摘要: Abstract Single conical nanopores were fabricated by etching single-ion-irradiated poly(ethylene terephthalate) (PET) films. The process was monitored measuring the transmembrane current. A series of with decreasing tip sizes (decreasing conductivity) obtained at different maximum currents, “ I max ”. Results showed that it possible to control diameter terminating a certain . current–voltage characteristic in KCl solution investigated. current rectification coefficient, γ = | ( U - ) / + , depended significantly on size: nanopore small could expect larger also influenced electrolyte concentration, and reached its concentration 0.3 M.
