Abstract
Inspired by the enchanting bioluminescence of fireflies, herein microfluidic droplet-based 'fireflies' for non-invasive biphasic chemical analysis are demonstrated. Bicompartmental droplets are created where a model analyte is transported from the aqueous compartment to the adjacent ionic liquid segment, yielding a bright fluid firefly structure via a localized catalytic reaction. Analysis of fluorescence emission kinetics and a method to passively decouple the two compartments at a constriction are presented. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
