Abstract: We present microfluidic droplet-based 'fireflies' for non-invasive chemical and biological sensing applications. These 'fireflies' are bi-compartmental aqueous-ionic liquid droplets in which metal (gold) ions from the aqueous compartment partition into the adjacent ionic liquid compartment and catalyze a fluorescence producing reaction. We report detailed measurements of the kinetics of fluorescence emission as a function of metal concentration and droplet flow speed. Finally, we demonstrate complete, passive detachment of the two compartments at a hydrodynamic obstruction. Copyright © (2011) by the Chemical and Biological Microsystems Society.
