Ruthenium Oxide pH Sensing for Organs-On-Chip Studies

Proceedings, 2018
A ruthenium oxide (RuOx) electrode is being developed as potentiometric pH sensor for organs-on-chip applications. Open-circuit potential (OCP) of the RuOx electrode showed a response of −58.05 mV/pH, with no cross-sensitivity to potentially ...
