Conductive events during nanopore sensing, are seen typically under low salt conditions and widely thought to arise from counterions brought into the pore via analyte. Here, authors show that an imbalance of ionic fluxes lead to conductive events.

The complexity of polysaccharides significantly complicates their analysis in comparison to other biopolymers. Here, the authors demonstrate that solid-state silicon nitride nanopore sensors can be used to reliably detect native polysaccharides and t

Protein sequencing, as well as protein fingerprinting, has gained tremendous attention in the electrical sensing realm of solid-state nanopores and is challenging due to fast translocations and the use of high molar electrolytes. Despite providing an

Electrolyte chemistry plays an important role in the transport properties of analytes through nanopores. Here, we report the translocation properties of the protein human serum transferrin (hSTf) in asymmetric LiCl salt concentrations with either pos

The pervasive model for a solvated, ion-filled nanopore is often a resistor in parallel with a capacitor. Although the simple model suggests that ionic current can flow through both components, under voltage-clamped conditions, capacitive currentshou

Nanopore probing of molecular level transport of proteins is strongly influenced by electrolyte type, concentration, and solution pH. As a result, electrolyte chemistry and applied voltage are critical for protein transport and impact, for example, c

Nanopores are a promising single-molecule sensing device class that captures molecular-level information through resistive or conductive pulse sensing (RPS and CPS). The latter has not been routinely utilized in the nanopore field despite the benefit
