Fabrication and practical applications of molybdenum disulfide nanopores

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

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 ...

Single-layer MoS2 nanopores as nanopower generators

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

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 ...

Identification of single nucleotides in MoS2 nanopores

Andras Kis, Aleksandra Radenovic, Roman Bulushev, Sergey Khlybov, Jiandong Feng, Ke Liu, Dumitru Dumcenco

The size of the sensing region in solid-state nanopores is determined by the size of the pore and the thickness of the pore membrane, so ultrathin membranes such as graphene and single-layer molybdenum disulphide could potentially offer the necessary spati ...
