Culturing barrier tissues such as endothelial and epithelial layers in bioreactors provides valuable models for drug transport and tissue integrity studies. However, conventional electrical resistance measurement methods often struggle to deliver accurate data in systems with fluid flow and dynamic conditions.
The research focused on developing titanium nitride (TiN)-coated electrodes that could be adapted for different bioreactor types, enabling non-invasive, continuous monitoring of tissue barrier integrity. Using these electrodes, researchers successfully tracked changes in blood-brain barrier models and intestinal cell cultures under flow conditions, opening doors for more reliable and versatile biological testing platforms.
