Since the emergence of microfluidic platforms sensors integration has been a major challenge. With the advances in miniaturization of these platforms, there is a need for solutions to integrate various optical components in order to build sensors, which will offer different detection characteristics such as several emission and sensing wavelengths. Moreover, the integration of an electrochemical sensor including a transparent electrode that will be compatible with the optical sensor represents an additional challenge. In this perspective, organic optoelectronic devices combined with silver nanowire electrodes could be a solution. The integration of a fluorescent sensor and an electrochemical oxygen sensor into a microfluidic platform and the different characteristics, advantages and disadvantages that offer organic light-emitting diodes (OLED), organic photodetectors (OPD) and silver nanowire electrodes are discussed. Finally, an example of the integration of an optical and an electrochemical sensor into a microfluidic chip for water pollution detection will be described.
自微流控平台出现以来，传感器集成一直是一项重大挑战。随着这些平台小型化的进展，需要解决方案来集成各种光学组件以构建传感器，这些传感器将提供不同的检测特性，例如多种发射和传感波长。此外，集成一个包括与光学传感器兼容的透明电极的电化学传感器是一项额外的挑战。从这个角度来看，有机光电器件与银纳米线电极相结合可能是一种解决方案。本文讨论了将荧光传感器和电化学氧传感器集成到微流控平台中，以及有机发光二极管（OLED）、有机光电探测器（OPD）和银纳米线电极所具有的不同特性、优点和缺点。最后，将描述一个将光学传感器和电化学传感器集成到用于水污染检测的微流控芯片中的示例。
