N2 - We present a micro-optofluidic device with an integrated optical fiber to enable real time electrolyte measurements. The target application is, in-line electrolyte monitoring during dialysis. The device is fabricated in PDMS (polydimethylsiloxane) using soft-lithography. The optical sensing principle is based on selective fluorescence quenching of PET (photoinduced electron transfer) ON-OFF process. We have covalently immobilized these PET sensor molecules on the PDMS microchannel walls. A proof-of-concept device is presented for sodium concentrations measurement in a flowing medium. The first results show a clear relation between sodium concentrations and fluorescence intensity.
