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 ...

Online monitoring of biofouling using coaxial stub resonator technique

Sensing and Bio-Sensing Research, 2015
Here we demonstrate the proof-of-principle that a coaxial stub resonator can be used to detect early stages of biofilm formation. After promising field tests using a stub resonator with a stainless steel inner conductor as sensitive element, the ...

Electrofusion of single cells in picoliter droplets

Scientific Reports, 2018
We present a microfluidic chip that enables electrofusion of cells in microdroplets, with exchange of nuclear components. It is shown, to our knowledge for the first time, electrofusion of two HL60 cells, inside a microdroplet.
