Modeling thermophoretic effects in solid-state nanopores [PDF]
Journal of Computational Electronics, 2014 Local modulation of temperature has emerged as a new mechanism for regulation of molecular transport through nanopores. Predicting the effect of such modulations on nanopore transport requires simulation protocols capable of reproducing non-uniform temperature gradients observed in experiment.

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement
Advanced Functional Materials, EarlyView.An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

Solid-State Nanopore Recognition and Measurement Using Shannon Entropy
IEEE Photonics Journal, 2011 Solid-state nanopores are structures that can be fabricated using the electron beam of a transmission electron microscope (TEM). Nanopores can be used to electrically detect individual DNA molecules, and they have the potential to be applied to genomic ...

Ionic current inversion in pressure-driven polymer translocation through nanopores [PDF]
, 2015 We predict streaming current inversion with multivalent counterions in hydrodynamically driven polymer translocation events from a correlation-corrected charge transport theory including charge fluctuations around mean-field electrostatics.

Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires
Advanced Functional Materials, EarlyView.Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...

Advanced Functional Materials, EarlyView.We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

Trapping DNA near a Solid-State Nanopore [PDF]
Biophysical Journal, 2012 We demonstrate that voltage-biased solid-state nanopores can transiently localize DNA in an electrolyte solution. A double-stranded DNA (dsDNA) molecule is trapped when the electric field near the nanopore attracts and immobilizes a non-end segment of the molecule across the nanopore orifice without inducing a folded molecule translocation.

Fabrication of Atomically Precise Nanopores in Hexagonal Boron Nitride [PDF]
, 2017 We demonstrate the fabrication of individual nanopores in hexagonal boron nitride (hBN) with atomically precise control of the pore size. Previous methods of pore production in other 2D materials create pores of irregular geometry with imprecise ...

Detecting DNA Depurination with Solid-State Nanopores
PLoS ONE, 2014 Among the different types of DNA damage that occur endogenously in the cell, depurination is especially prevalent. These lesions can initiate mutagenesis and have been implicated in a variety of diseases, including cancer. Here, we demonstrate a new approach for the detection of depurination at the single-molecule scale using solid-state nanopores.
