AB - Single nanometer-sized pores embedded in an insulating membrane are an exciting new class of nanosensors for rapid electrical detection and characterisation of biomolecules [1]. In most cases, the fabrication of such nanopores requires the high-energy beam of a transmission electron microscope (TEM) or focused ion beam (FIB) tool to drill or reshape a small hole in a freestanding membrane [1,2]. Here, we present a novel method to reduce the size of such pores using electrochemical deposition with ionic current feedback control. Electrophoretic transport of λ-DNA through the electrodeposited nanopores is also demonstrated using electrical detection. © 2009 CBMS.
