Static and Dynamic Optical Analysis of Micro Wrinkle Formation on a Liquid Surface

Micromachines, 2021
A spatially periodic voltage was used to create a dielectrophoresis induced periodic micro wrinkle deformation on the surface of a liquid film. Optical Coherence Tomography provided the equilibrium wrinkle profile at submicron accuracy.

Remote‐Controlled Release of Nitric Oxide by Plasmonic Waveguide Coated With Metal–Organic Frameworks

Small, EarlyView.
Remote‐controlled intracellular delivery is achieved using a plasmonic waveguide coated with a photoresponsive NO‐releasing MOF. Surface plasmon polariton propagation remotely induces photocleavage and localized nitric oxide release in a target single live cell without direct light exposure, while biological relevance is demonstrated through transient ...

Discriminating Between Living and Dead Bacteria With a Field‐Effect Transistor Based on Nano‐Channels

Small, EarlyView.
Bacterial viability is determined in a complex environment with a field‐effect biological transistor with a limit of detection of a single bacterium. Living, antibiotic‐treated, thermally denatured, and inhibited E. coli generate distinct electrical signatures, enabling label‐free single‐cell detection and providing new opportunities for rapid ...

Possibilities of the method of dielectrophoresis of erythrocytes in distinction of patients with fatty liver disease of alcoholic and non-alcoholic genesis

Атеросклероз, 2020
The aim of the work is to study the possibilities of distinguishing between men with fatty disease of alcoholic and non-alcoholic origin using the viscoelastic parameters of erythrocytes - deformation amplitude, summerized indicators of viscosity and ...

Active control of Lubricant Flow Using Dielectrophoresis and Its Effect on Friction Reduction

Tribology Online, 2023
With the increasing demand for active friction control, we newly proposed to use dielectrophoresis to change the flow of PG-droplet-containing PAO4 to reduce the friction coefficient. The friction result with a 1-mm roller shows 20% reduction in friction

Three‐Dimensional Optical and Computational Reconstruction of Colloidal Electrokinetic Flows via Multiplane Imaging and Multiscale Modeling

Small, EarlyView.
Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...

Nucleotide Identification in DNA Using Dielectrophoresis Spectroscopy

Micromachines, 2019
We show that negative dielectrophoresis (DEP) spectroscopy is an effective transduction mechanism of a biosensor for the detection of single nucleotide polymorphism (SNP) in a short DNA strand. We observed a frequency dependence of the negative DEP force

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.
