A Floating Capsule Electrochemical System for In Situ and Multichannel Ion-Selective Sensing.

ABSTRACT: Free-floating electrochemical sensors are promising for in situ bioprocess monitoring with the advantages of movability, a lowered risk of contamination, and a simplified structure of the bioreactor. Although floating sensors were developed for the measurement of physical and chemical indicators such as temperature, velocity of flow, pH, and dissolved oxygen, it is the lack of available electrochemical sensors for the determination of the inorganic ions in bioreactors that has a significant influence on cell culture. In this study, a capsule-shaped electrochemical system (iCapsuleEC) is developed to monitor ions including K⁺, NH₄⁺, Na⁺, Ca²⁺, and Mg²⁺ based on solid-contact ion-selective electrodes (SC-ISEs). It consists of
