A Frequency-Domain Optofluidic Dissolved Oxygen Sensor With Total Internal Reflection Design For in Situ Monitoring

Abstract

Continuous measurement of dissolved oxygen (DO) variation is important in water monitoring and biomedical applications, which require low-cost and low-maintenance sensors capable of automated operation. A frequency-domain optofluidic DO sensor with total internal reflection (TIR) design has been developed based on fluorescence quenching of Ruthenium complex (Ru(dpp)3Cl2). To minimize artifacts causing drift in fluorescence measurements such as …
