Dynamic and Stimuli-Responsive Multi-Phase Emulsion Droplets for Optical Components

Emulsion morphologies enable dynamic optical phenomena, such as refractive micro-optical components with variable optical properties and total internal reflection-enabled light interference. This work facilitates the use of light-emitting emulsion morphologies as chemo-optical transducers for early-stage food-borne pathogen detection.

This thesis explores the potential of emulsion morphologies to enable a wide range of dynamic optical phenomena. Despite the highly dynamic nature of fluid morphologies and their applications in stimuli-responsive, dynamic optical materials and devices, fluid matter is underrepresented in optical technology. By utilizing bi-phase emulsion droplets as refractive micro-optical components, this thesis achieves the realization of micro-scale fluid compound lenses with optical properties that can be tailored in response to changes in chemical concentrations, structured illumination, and thermal gradients. Theoretical considerations of emulsions as optical components shed light on a previously unrecognized phenomenon of light interference in emulsion droplets, resulting in rich structural coloration. While this work primarily focuses on the fundamental optics of emulsion droplets, it also facilitates the use of light-emitting emulsion morphologies as chemo-optical transducers for early-stage food-borne pathogen detection. This thesis showcases the benefits of interdisciplinary exploration of unconventional material systems at the intersection of optics, chemistry, and materials science, and the translation of acquired knowledge into specific application scenarios.

This thesis builds on recent innovations in multi-phase emulsion droplet design to demonstrate that emulsion morphologies enable a useful variety of dynamic optical phenomena.
