Simple Fabrication of Solid-State Nanopores on a Carbon Film

Micromachines, 2021
Solid-state nanopores are widely used as a platform for stochastic nanopore sensing because they can provide better robustness, controllable pore size, and higher integrability than biological nanopores.

Noise in solid-state nanopores [PDF]

Proceedings of the National Academy of Sciences, 2008
We study ionic current fluctuations in solid-state nanopores over a wide frequency range and present a complete description of the noise characteristics. At low frequencies ( f ≲ 100 Hz) we observe 1/ f -type of noise.

Diameter distribution and formation mechanism of solid-state nanopores prepared by dielectric breakdown

AIP Advances, 2021
The diameter distribution and dielectric breakdown mechanism of solid-state nanopores in a liquid environment are discussed based on the experimental results. We discussed the nanopore formation mechanism from the viewpoint of the statistical correlation

Field effect control of translocation dynamics in surround-gate nanopores

Communications Materials, 2021
Controlling the speed of electrophoresis across a solid-state nanopore is crucial for single-molecule sensing and sequencing. Here, a gate-controlled nanopore is able to trap and slow-down the translocation dynamics of nanoparticles by balancing the ...

Manipulation of DNA transport through solid-state nanopores by atomic force microscopy

Materials Research Express, 2020
To realize DNA sequencing by a solid-state nanopore, the translocation speed of DNA through the nanopore should be slowed down to obtain the temporal resolution.
