Multiphase microscale emulsions are a material platform that can be tuned and dynamically configured by a variety of chemical and physical phenomena, thus rendering them inexpensive and broadly programmable optical transducers for a wide range of sensing scenarios. Herein, multiphilic triblcok copolymer surfactants are developed to manipulate the biphasic emulsion shape and optical behavior. Site-specific conjugation of gold nanoparticles affords the creation of gold rings along the tri-phase junction of the emulsions, which amplifies the amount of light available for total internal reflection interference and isotropize the structural colors. Dynamic behavior of complex emulsions is imparted to the gold rings, affording the visualization of emulsion shape into the specific color reflection. |
