Real-Time Monitoring of Stem Cells by Diamond-Based Impedance Sensors

open access: yesProceedings, 2017
Cell-based impedance spectroscopy is a promising label-free method for electrical monitoring of cell activity. Here we present a diamond-based impedance sensor with built-in gold interdigitated electrodes (IDEs) as a promising platform for simultaneous ...

On-Chip Detection of Beads with a New Electrical Impedance Sensor [PDF]

open access: yes, 2010
Electrical impedance measurements in microfluidic chips are used for single cell analysis. Parallel electrodes are more suited than planar ones since the electrical field distribution is more homogenous.

Microfluidic Electrical Impedance Spectroscopy

open access: yes, 2020
The goal of this study is to design and manufacture a microfluidic device capable of measuring changes in impedance valuesof microfluidic cell cultures. Tocharacterize this, an interdigitated array of electrodes was patterned over glass, where it was then bonded to a series of fluidic networks created in PDMS via soft lithography.
