Model of an Interdigitated Electrodes System for Cell Counting Based on Impedance Spectroscopy
Introduction: A cell counter sensor based on impedance spectroscopy has been modeled by means of COMSOL Multyphisics 4.2a. The cell counter consists in a system of vertical interdigitated electrodes, built on a silicon wafer by means of microfabrication technologies (Figure 1). With the aim to overcome the critical limiting factor of the low throughput characterizing the existing cell counters,...
متن کاملFlexible Pressure Sensor with Ag Wrinkled Electrodes Based on PDMS Substrate
Flexible pressure sensors are essential components of electronic skins for future attractive applications ranging from human healthcare monitoring to biomedical diagnostics, robotic skins, and prosthetic limbs. Here we report a new kind of flexible pressure sensor. The sensors are capacitive, and composed of two Ag wrinkled electrodes separated by a carbon nanotubes (CNTs)/polydimethylsiloxane ...
متن کاملComparison of ITO and IrOx-Modified ITO Interdigitated Electrodes for Electrical Cell-Substrate Impedance Sensing (ECIS) Applications
This study compares the sensitivity of interdigitated electrodes (IDEs) used in Electrical CellSubstrate Impedance Sensing (ECIS). IDEs made of indium tin oxide (ITO) and ITO coated with iridium oxide (IrOx) were used for ECIS measurements with the human breast cancer cell line, MCF-7. The results indicate that IrOx-modified ITO electrodes provide both biocompatibility and higher cell sensitivi...
متن کاملInterdigitated microelectrode (IME) impedance sensor for the detection of viable Salmonella typhimurium.
Interdigitated microelectrodes (IMEs) were used as impedance sensors for rapid detection of viable Salmonella typhimurium in a selective medium and milk samples. The impedance growth curves, impedance against bacterial growth time, were recorded at four frequencies (10Hz, 100Hz, 1kHz, and 10kHz) during the growth of S. typhimurium. The impedance did not change until the cell number reached 10(5...
