Nanopores in atomically thin 2D nanosheets limit aqueous ssDNA transport
Alex Smolyanitsky, Binquan Luan
Nanopores in 2D materials are highly desirable for DNA sequencing, yet achieving single-stranded DNA (ssDNA) transport through them is challenging. Using density functional theory…
Ion transport across solid-state ion channels perturbed by directed strain
A. Smolyanitsky, A. Fang, A. F. Kazakov +1
We combine quantum-chemical calculations and molecular dynamics simulations to consider aqueous ion flow across non-axisymmetric nanopores in monolayer graphene and MoS. When t…
Mechanosensitive ion permeation across sub-nanoporous MoS monolayers
A. Fang, K. Kroenlein, A. Smolyanitsky
We use all-atom molecular dynamics simulations informed by density functional theory calculations to investigate aqueous ion transport across sub-nanoporous monolayer molybdenum di…
Aqueous ion trapping and transport in graphene-embedded 18-crown-6 ether pores
A. Smolyanitsky, E. Paulechka, K. Kroenlein
Using extensive room-temperature molecular dynamics simulations, we investigate selective aqueous cation trapping and permeation in graphene-embedded 18-crown-6 ether pores. We sho…
Graphene deflectometry for sensing molecular processes at the nanoscale
Daniel Gruss, Alex Smolyanitsky, Michael Zwolak
Single-molecule sensing is at the core of modern biophysics and nanoscale science, from revolutionizing healthcare through rapid, low-cost sequencing to understanding various physi…
Relaxation-limited electronic currents in extended reservoir simulations
Daniel Gruss, Alex Smolyanitsky, Michael Zwolak
Open-system approaches are gaining traction in the simulation of charge transport in nanoscale and molecular electronic devices. In particular, "extended reservoir" simulations, wh…
A MoS2-based capacitive displacement sensor for DNA sequencing
A. Smolyanitsky, B. I. Yakobson, T. A. Wassenaar +2
We propose an aqueous functionalized molybdenum disulfide nanoribbon suspended over a solid electrode as the first capacitive displacement sensor aimed at determining the DNA seque…
Nucleobase-functionalized graphene nanoribbons for accurate high-speed DNA sequencing
Eugene Paulechka, Tsjerk A. Wassenaar, Kenneth Kroenlein +2
We propose a water-immersed nucleobase-functionalized suspended graphene nanoribbon as an intrinsically selective device for nucleotide detection. The proposed sensing method combi…
Effects of surface compliance and relaxation on the frictional properties of lamellar materials
Alex Smolyanitsky, Shuze Zhu, Zhao Deng +2
We describe the results of atomic-level stick-slip friction measurements performed on chemically-modified graphite, using atomic force microscopy (AFM). Through detailed molecular…
