Fabrication and practical applications of molybdenum disulfide nanopores

Aleksandra Radenovic, Martina Lihter, Mukeshchand Thakur, Michael Graf, Ke Liu, Jiandong Feng

Among the different developed solid-state nanopores, nanopores constructed in a monolayer of molybdenum disulfide (MoS2) stand out as powerful devices for single-molecule analysis or osmotic power generation. Because the ionic current through a nanopore is ...

2D MoS2 nanopores: ionic current blockade height for clustering DNA events

Aleksandra Radenovic, Ke Liu

2D nanopores can be used to electrophoretically drive DNA molecules, which can in turn be identified through measurable electronic current blockades. In this work, we use experimental data from molybdenum disulfide nanopores threading DNA nucleotides and p ...

In addition to their use in DNA sequencing, ultrathin nanopore membranes have potential applications in detecting topological variations in deoxyribonucleic acid (DNA). This is due to the fact that when topologically edited DNA molecules, driven by electro ...

Geometrical Effect in 2D Nanopores

Aleksandra Radenovic, Andras Kis, Duncan Thomas Lindsay Alexander, Vasiliki Tileli, Dumitru Dumcenco, Martina Lihter, Ke Liu, Davide Deiana, Aditya Sarathy

A long-standing problem in the application of solid-state nanopores is the lack of the precise control over the geometry of artificially formed pores compared to the well-defined geometry in their biological counterpart, that is, protein nanopores. To date ...

Supercritical CO2 injection and residence time in fluid-saturated rocks: Evidence for CO2 and mineral dissolution and effects on rock integrity

Lucas Xan Pimienta, Ke Liu

CO2 injection and storage in geological reservoirs is an attractive prospect for mitigating the anthropogenic production of greenhouse gases and global warming. The technology could lead to mineral precipitation and therefore stable storage over geological ...

Single-layer MoS2 nanopores as nanopower generators

Aleksandra Radenovic, Andras Kis, Dumitru Dumcenco, Michael Graf, Ke Liu, Dmitry Ovchinnikov, Jiandong Feng

Making use of the osmotic pressure difference between fresh water and seawater is an attractive, renewable and clean way to generate power and is known as 'blue energy'(1-3). Another electrokinetic phenomenon, called the streaming potential, occurs when an ...

Observation of ionic Coulomb blockade in nanopores

Aleksandra Radenovic, Andras Kis, Dumitru Dumcenco, Michael Graf, Ke Liu, Jiandong Feng, Massimiliano Di Ventra

Emergent behaviour from electron-transport properties is routinely observed in systems with dimensions approaching the nanoscale(1). However, analogous mesoscopic behaviour resulting from ionic transport has so far not been observed, most probably because ...
