Structural coloration plays an important role in daily phenomena as one of the main mechanisms of color in nature and materials. Complex emulsion droplets consisting of hydrocarbon and fluorocarbon oils have previously been shown to exhibit iridescent structural color via total internal reflection based on the size, shape, composition, and orientation of the droplets. Our study works to further explore the optical properties of complex emulsion droplets and their applications given their reconfigurable properties in aqueous surfactant solution. An α – amylase enzyme-responsive surfactant solution was modeled after a previous study by Zarzar, et al. and is composed of e, γ – cyclodextrin substrate, Triton X – 100 surfactant, and Capstone FS – 30 surfactant. This enzyme-responsive surfactant solution was utilized to quantify the sensitivity of O/O/W emulsion droplets for simple colorimetric sensing capabilities and enzyme activity through the correlation of color patterns to droplet shape, size, and volume ratio.
