OPTICAL RESONANCES IN DROPLETS IN A MICROCHANNEL

摘要

Methods and a microchannel apparatus form microdroplets that enable internal reflection within the droplets sufficient to support morphology dependent resonances. The morphology dependent resonances can be used for detecting an analyte of interest within the droplets according to various known methods. The droplets comprise glycerol and a fluorescent dye, and when excited by a pulsed laser, strong resonances and lasing are established inside the droplet. The microdroplet acts as a high quality factor optical cavity that supports morphology dependent resonances (MDRs). Enhanced radiative energy transfer is mediated through these optical resonances.
