Mechanisms of focused ion beam (FIB) material removal and rearrangement at high beam flux
… from electron microscope sample preparation to nanopore processing for DNA sequencing. Despite the wide spread use of FIB, the basic material removal mechanisms are not well understood and may depend upon FIB operations. We present the first complete atomistic simulation of high-flux FIB using …

Silicon nanopore patch clamp device for measuring single ion channel activity
… Here we have developed a novel silicon nanopore planar patch clamp chip that is ideal for single ion channel measurements because the nanopore apertures minimize cell membrane capacitance, reduce chip capacitance, reduce cell membrane damage, and allow for work with smaller cells. Here …

Ion transport across individual sub-continuum graphene nanopores : phenomenology, theory, and implications for industrial separations
… graphene, provide a new class of solid-state nanopores - apertures that allow for the exchange of matter across thin membranes - with the smallest possible volumes of any ion channel. As the diameter of these nanopores becomes comparable to that of hydrated ions, sub-continuum effects have the …

Design and fabrication of asymmetric nanopores using pulsed PECVD
… and biological applications. Structures such as nanopores demonstrate a phenomenon known as hindered transport which can be exploited in analytical applications such as DNA sequencing, ionic transistors, and molecular sieving. Precisely controlling the size, geometry and surface characteristics …

DNA translocation through an array of kinked nanopores
Synthetic solid-state nanopores are being intensively investigated as single-molecule sensors for detection and characterization of DNA, RNA, and proteins. This field has been inspired by the exquisite selectivity and flux demonstrated by natural biological channels and the dream of emulating these …
