Identification of single nucleotides in MoS2 nanopores.
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 spatial resolution for nanopore DNA sequencing. However, the fast translocation speeds (3,000-50,000 nt ms(-1)) of DNA molecules moving across suc...

متن کاملElectrochemical Reaction in Single Layer MoS2: Nanopores Opened Atom by Atom.
Ultrathin nanopore membranes based on 2D materials have demonstrated ultimate resolution toward DNA sequencing. Among them, molybdenum disulfide (MoS2) shows long-term stability as well as superior sensitivity enabling high throughput performance. The traditional method of fabricating nanopores with nanometer precision is based on the use of focused electron beams in transmission electron micro...
متن کاملAtomically thin molybdenum disulfide nanopores with high sensitivity for DNA translocation.
Atomically thin nanopore membranes are considered to be a promising approach to achieve single base resolution with the ultimate aim of rapid and cheap DNA sequencing. Molybdenum disulfide (MoS2) is newly emerging as a material complementary to graphene due to its semiconductive nature and other interesting physical properties that can enable a wide range of potential sensing and nanoelectronic...

Remarkable Activity and Stability of Photocatalytic Hydrogen Production over Dye-Sensitized Single Molecular Layer MoS2 Ensemble Experimental Preparation of S-MoS2 Single-layer MoS2 was synthesized by the exfoliation of MoS2 with lithium intercalation[1]. The starting material used in the reported studies was bulk MoS2 powder from Sigma Aldrich. 500 mg of the black MoS2 powder was first soaked ...
