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.

Photothermal bubble: Dynamics, manipulation, and applications

Droplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

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

Nanoelectronic Detection of Opioids: Machine Learning‐Powered Screening With Carbon Nanotube Field‐Effect Transistor Sensor Array

Small, EarlyView.
A carbon nanotube field‐effect transistor (NTFET) sensor array is constructed to screen different opioids with machine learning models. Codeine, fentanyl, hydrocodone, and morphine are tested using the NTFET sensor array and classified with both conventional supervised learning models and deep learning models.

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

Separation of Submicron Bioparticles by Dielectrophoresis [PDF]

Biophysical Journal, 1999
Submicron particles such as latex spheres and viruses can be manipulated and characterized using dielectrophoresis. By the use of appropriate microelectrode arrays, particles can be trapped or moved between regions of high or low electric fields. The magnitude and direction of the dielectrophoretic force on the particle depends on its dielectric ...
