光学化学传感器能够连续记录化学物质，因此在化学工业、生物技术和医学等领域已经发现（并将发现）许多应用。在用于传感目的的许多光学方法中，荧光引起了特别的关注，因为它是敏感的，具有许多参数，可以作为分析信息，并知道其他光谱学未知的影响。然而，由于缺乏适当的材料，包括聚合物和颗粒、指示剂探针、分子受体、载体、催化剂和荧光半导体材料，光谱方案到有用的传感方案中的实施受到阻碍。本文将讨论过去几年取得的进展以及未来的一些方面和挑战。
Optical chemical sensors are capable of continuously recording a chemical species and thus have found ( and will find) numerous applications in areas such as the chemical industry, in biotechnology and medicine. Among the many optical methods are employed for sensing purposes, fluorescence has attracted particular attention because it is sensitive, has numerous parameters that can serve as an analytical information and knows effects unknown to other spectroscopies. The implementation of spectroscopic schemes into a useful sensing scheme has been hampered though, by the lack of appropriate materials including polymers and particles, indicator probes, molecular receptors, carriers, catalysts and fluorescent semiconductor materials. This article will address the progress made in the past years and some of the futures aspects and challenges.
