Solid-state nanopores have been used extensively over the past decade as powerful tools to study the structure and dynamics of single molecules of DNA. The use of nanopores has mostly been confined to the study of DNA due to the hope that they may eventually be used to cheaply sequence DNA. We have begun extending nanopores to the study of protein filaments, specifically filamentous actin (Fact...

Nanopores--nanosized holes that can transport ions and molecules--are very promising devices for genomic screening, in particular DNA sequencing. Solid-state nanopores currently suffer from the drawback, however, that the channel constituting the pore is long, approximately 100 times the distance between two bases in a DNA molecule (0.5 nm for single-stranded DNA). This paper provides proof of ...

We analyze electronic and phononic quantum transport in zigzag or chiral graphene nanoribbons (GNRs) perforated with an array of nanopores. Since local charge current profiles in these GNRs are peaked around their edges, drilling nanopores in their interior does not affect edge charge currents while drastically reducing the phonon heat current in sufficiently long wires. The combination of thes...

Single molecule studies using nanopores have gained attention due to the ability to sense single molecules in aqueous solution without the need to label them. In this study, short DNA molecules and proteins were detected with glass nanopores, whose sensitivity was enhanced by electron reshaping which decreased the nanopore diameter and created geometries with a reduced sensing length. Further, ...

Nanoporous alumina which was produced by a conventional direct current anodization [DCA] process at low temperatures has received much attention in various applications such as nanomaterial synthesis, sensors, and photonics. In this article, we employed a newly developed hybrid pulse anodization [HPA] method to fabricate the nanoporous alumina on a flat and curved surface of an aluminum [Al] fo...

Abstract Nanopores constitute an important class of biotechnologically relevant proteins. Unlike binders and enzymes, their experimental characterization is limited to high-resolution, yet low throughput biophysical methods. Addressing this technological gap, the functional nanopore (FuN) screen now provides a versatile assay study engineer nanopores in Escherichia coli combining quantitative r...

Solid-state nanopores are widely acknowledged as tools with which to study local structure in biological molecules. Individual molecules are forced through a nanopore, causing a characteristic change in an ionic current that depends on the molecules' local diameter and charge distribution. Here, the translocation measurements of long (~5-30 kilobases) single-stranded poly(U) and poly(A) molecul...
