Ion transport through nanopores is an important process in nature and has engineering applications. To date, most studies of nanopore ion have been carried out with electrolytes relatively low concentrations. In this paper, we report on ionic current modulation from the translocation dsDNA a under high strength electrolyte concentration gradient across nanopore. Results show that case, DNA can induce either negative or positive modulation, even though usually only downward peaks are expected...
The practical issues (reproducibility, time and pore size control) for massive fabrication of nanopores over a wafer several inches biomolecule detection are addressed here.
Solid-state nanopores have become a prominent tool in the field of single-molecule detection. Conventional solid-state are thick, which affects spatial resolution detection results. Graphene is thinnest 2D material and has highest resolution. In this study, graphene membrane chip was fabricated by combining MEMS process with wet transfer process. Raman spectroscopy used to assess quality after transfer. The mechanism behind influence processing dose residence time helium ion beam on...
A series of nanopores with diameters ranging from 2.5 to 63 nm are fabricated on a reduced $\mathrm{S}{\mathrm{i}}_{3}{\mathrm{N}}_{4}$ membrane by focused ion beam and high energy electron beam. Through measuring the blocked ionic currents for DNA strands threading linearly through those solid-state nanopores, it is found that blockade current proportional square hydrodynamic diameter strand. With nanopore be comparable strands, becomes smaller, which attributed size confinement effects....
Metal-assisted chemical etching (MACE) is a simple, low-cost method for fabricating silicon nanostructures. In this paper, the recent progress of MACE to control nanostructures reviewed. The principle briefly summarized. main influencing factors which decided process and final morphology, such as metal substrate (type, deposition mode, distribution morphology), etchant concentration, temperature, time, light intensity (doping type, doping level) are also discussed. Finally, existing...
Diamond is renowned as the ultimate semiconductor thanks to its exceptional physical properties, including unmatched hardness, wear resistance, superior mechanical and tribological characteristics, high fracture strength. solution-gate field-effect transistors (D-SGFETs) leverage these advantages, along with their outstanding high-power high-frequency performance, excellent thermal conductivity, wide bandgap, carrier mobility, rapid saturation speed. These features make D-SGFETs highly...
Two-dimensional molybdenum disulfide is gradually emerging as the novel semiconductor material(channel) to connect two electrodes (source and drain) of field-effect transistor. For effective detecting biological molecules, a newly liquid-gated transistor was fabricated in this paper. Molybdenum film transferred cover silicon nitride substrate on which drain source were deposited. The through hole created back substrate. Then immersed electrolyte, NaCl solution gate. electrical...
Effective and universal method to fabricate site well-defined, ordered, homogenous size SiNWs is still necessary support application. In this paper, a simple cost-effective approach synthesis controlled amorphous silicon nanowires (a-SiNWs) reported. The position of a-SiNWs array can be simply by the micron Cu patterns through photolithography. While adjust volume pattern.
In this paper, amorphous silicon nanowires (α-SiNWs) were synthesized on (100) Si substrate with oxide film by Cu catalyst-driven solid-liquid-solid mechanism (SLS) during annealing process (1080 °C for 30 min under Ar/H2 atmosphere). Micro size pattern fabrication decided whether α-SiNWs can grow or not. Meanwhile, those micro patterns also controlled the position and density of wires. During process, reacted SiO2 to form silicide. More important, a diffusion channel was opened atoms...
The two-dimensional layer of Molybdenum disulfide (MoS2) has attracted much interest due to its direct-gap property and potential applications in the field catalysis, nanotribology, microelectronics, lithium batteries, hydrogen storage, medical, high-performance flexible electronics optoelectronics. In this paper, based on few-layer MoS2 acquired by mechanical exfoliation method, a liquid-gated effect transistor (L-FET) is fabricated. Simultaneously, characterized Raman spectral. Then,...
