Such compound micro-lenses may be composed of two or more components (e.g., two or more inner phases) that form stable bi-phase emulsion droplets in outer phases (e.g., aqueous media). In some embodiments, the articles described herein may be useful as light emitting droplets. Advantageously, the plurality of droplets may be configured such that light rays may modified (e.g., via stimulation of the droplets, exposure to an analyte such as a pathogen) to have a detectable emission intensity and/or angle of maximum emission intensity under a particular set of conditions.
