Sensors and methods for determination of analytes are provided. Analytes including explosives (e.g., RDX or PETN) may be determined by monitoring, for example, a change in an optical signal of a material upon exposure to the analyte. In some embodiments, the analyte and the material may interact via a chemical reaction to form a new emissive species. Embodiments described herein may provide inexpensive sensors with high selectivity and sensitivity.
提供了用于测定分析物的传感器和方法。例如,可以通过监测物质在暴露于分析物(例如RDX或PETN)时的光信号变化来确定分析物。在某些实施例中,分析物和物质可以通过
化学反应相互作用以形成新的发射物种。本文所述的实施例可能提供价格便宜、选择性和灵敏度高的传感器。
