Collection description

Electrical impedance sensing of biological systems is now a common technique to monitor cell motion, morphology, and cell layer/tissue integrity for high throughput toxicology screening. Existing methods to measure electrical impedance most often rely on a two or four electrode configuration, where low frequency signals are challenging to obtain for small devices and for tissues with high resistance, due to low current. Here, we propose a microfluidic PDMS platform integrated with an array of organic electrochemical transistor (OECT) that will allow us to monitor the transendothelial electrical resistance (TEER) with sensitivity higher than the one achieved using common electrode configurations. This platform may have potential as a method for the measurement of compound toxicology in vitro and for diagnostics.
