摘要

Asymmetric conically shaped nanochannels fabricated by ion-track-etching have been proved to be a versatile platform for biosensor and single molecule analysis[1-4].Just as biological nanochannels,single conical nanopores possess some special physicochemical functions,such as ion selectivity,current rectification and current switch[5;6].This work presents the recent characteristic study of the polymer nanopores prepared by single ion hits.PET(polyethylene terephthalate)membranes(diameter=25 mm,thickness=13μm)were irradiated with a heavy 86Kr26+ions of 25 MeV/u energy at the Lanzhou Interdisciplinary Heavy Ion Microbeam(LIHIM)to create a single damage track through the membrane.
