Ion-modulated interfacial fluorescence in droplet microfluidics using an ionophore-doped oil

This content is a preprint and has not undergone peer review at the time of posting.

Abstract

Fluorescence at the oil-water interface is used for chemical sensing in droplet microfuidics. Potassium ions in aqueous droplets are extracted into oil segments doped with an ionophore, a cation exchanger, and a cationic dye to displace the dye to the thin interface, allowing for highly sensitive and selective turn-on sensing of ions.
