We report on a new modular sensing approach in which complex emulsions serve as efficient transducers in optical evanescent field-based sensing devices. Specifically, we leverage the tunable refractive index upon chemically triggered changes in droplet morphology or orientation. Variations in the optical coupling result in readily detectable changes in the light transmitted from a waveguide.
我们报告了一种新的模块化传感方法，其中复杂乳液在基于光消逝场的传感设备中充当高效换能器。具体而言，我们利用在液滴形态或取向发生化学触发变化时可调折射率。光学耦合的变化导致从波导传输的光中发生易于检测的变化。
