Impedance Biosensor


We aim to generate cell based biosensors to extrapolate the hazardous effects of chemicals and contaminated water samples on fish health. The culture of rainbow trout (Oncorhynchus mykiss) cell lines in impedance sensing biochips herein enables to detect the critical, dose-dependent momentum of irreversible intoxication.

Bio-impedance spectroscopy provides information on the electrical properties of cells, which can directly be linked to cell viability. Currently we are establishing static and flow-based sensors for chemical hazard assessment and a portable sensor for field application.
