本文综述了基于离子载体的光学传感器（IBOS）设计的关键方面。建立了精确的响应函数，并与简化的广义方程进行了比较。我们还简要介绍了不太成熟但很有前途的工作原理，即动态响应和穷举交换。吸光度和荧光是用于评估传感器响应的主要光学读出策略，但它们通常需要一个强大的参考技术用于现实世界的应用。本文还讨论了基于IBOS和其他光学传感器的参考方案。最后，从动态可切换IBOS和再生穷尽交换IBOS的角度对近年来发展的光响应离子提取/释放系统的性能进行了概述和讨论。
This review provides an overview of the key aspects of designing ionophore-based optical sensors (IBOS). Exact response functions are developed and compared with a simplified, generalized equation. We also provide a brief introduction into less established but promising working principles, namely dynamic response and exhaustive exchange. Absorbance and fluorescence are the main optical readout strategies used in the evaluation of a sensor response, but they usually require a robust referencing technique for real-world applications. Established referencing schemes using IBOS as well as those from other optical sensors are also discussed. Finally, the power of recently developed photoresponsive ion extraction/release systems is outlined and discussed in view of dynamically switchable IBOS or regenerative exhaustive exchange IBOS.
