Multimodal imaging is a powerful and versatile approach that integrates and correlates multiple optical modalities within a single device. This concept has gained considerable attention due to its potential applications ranging from sensing to medicine. Herein, we develop several wireless multimodal light-emitting chemical systems by coupling two light sources based on different physical principles: electrochemiluminescence (ECL) occurring at the electrode interface and a light-emitting diode (LED) switched on by an electrochemically triggered electron flow. Endogenous (thermodynamically spontaneous redox process) and exogenous (requiring an external power source) bipolar electrochemistry acts as a driving force to trigger both light emissions at different wavelengths. The results presented here interconnect optical imaging and electrochemical reactions, providing a novel and so far unexplored alternative to design autonomous hybrid systems with multimodal and multicolor optical readouts for complex bio-chemical systems.
多模态成像技术是一种强大且通用的方法，它能在单一设备中整合多种光学模态并建立它们之间的关联。由于其从传感到医学等潜在应用领域，这一概念已受到广泛关注。在此，我们通过耦合基于不同物理原理的两种光源，开发了几种无线多模态发光化学系统：电极界面发生的电化学发光（ECL）和由电化学触发的电子流开启的发光二极管（LED）。内源性（热力学自发氧化还原过程）和外源性（需要外部电源）双极电化学作为驱动力，触发不同波长的两种发光。本文展示的结果将光学成像与电化学反应相互连接，为设计用于复杂生化系统的具有多模态和多色光学读数的自主混合系统提供了一种新颖且尚未探索的替代方案。
