Interfacial Electric Effects on a Non-Isothermal Electroosmotic Flow in a Microcapillary Tube Filled by Two Immiscible Fluids

Micromachines, 2017
In this work, a non-isothermal electroosmotic flow of two immiscible fluids within a uniform microcapillary is theoretically studied. It is considered that there is an annular layer of a non-Newtonian liquid, whose behavior follows the power-law model ...

Identification and Discrimination of Sulfated and Unsulfated Gut‐Hormone Biomarkers in Human Serum by Nanopore

Small, EarlyView.
This study discriminates between sulfated and unsulfated cholecystokinin‐8 gut‐hormone forms at single‐molecule‐level resolution. Using an aerolysin nanopore embedded in a hybrid lipid‐polymer membrane, the system produces distinct electrical signatures enabling highly sensitive detection, even in 20% human serum.

Electroosmotic Flow Hysteresis for Dissimilar Anionic Solutions [PDF]

Analytical Chemistry, 2015
Electroosmotic flow (EOF) with two or more fluids is commonly encountered in various microfluidics applications. However, no investigation has hitherto been conducted to investigate the hysteretic or flow direction-dependent behavior during the displacement flow of solutions with dissimilar ionic species.

How We Simulate Nanopores

Small Methods, EarlyView.
Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

Microfluidic Sample Compartmentalization for Biomolecular Concentration Quantification Using a Nanopore Sensor

Small Methods, EarlyView.
We compartmentalize samples into picoliter volumes using a microfluidic device, allowing us to determine biomolecular concentration by counting molecules to depletion within a known volume without calibration. By integrating a nanopore sensor for this counting process, we also obtain real‐time data on the size, shape, and conformation of each ...
