Concentration Polarization of High Concentration Solution in Sub-nm Nanopore [PDF]

E3S Web of Conferences, 2021
The behavior of ion transport through the sub-nm nanopores on the film is is different from the behavior of bulk behavior. Many intriguing phenomena in ionic transport are the key to the design and fabrication of solid-state nanofluidic devices. However,

Solid-state nanopore hydrodynamics and transport [PDF]

Biomicrofluidics, 2019
The resistive pulse method based on measuring the ion current trace as a biomolecule passing through a nanopore has become an important tool in biotechnology for characterizing molecules. A detailed physical understanding of the translocation process is essential if one is to extract the relevant molecular properties from the current signal.

Nanobubbles in Solid-State Nanopores

Physical Review Letters, 2006
From conductance and noise studies, we infer that nanometer-sized gaseous bubbles (nanobubbles) are the dominant noise source in solid-state nanopores. We study the ionic conductance through solid-state nanopores as they are moved through the focus of an infrared laser beam.
