    • A sensor has a sensor substance, an electromagnetic energy source, and a detector. The sensor substance may be able to emit electromagnetic energy different than that provided by the energy source when an analyte of interest is in contact with the sensor substance and electromagnetic energy is received by the sensor substance. The energy source and the detector may be provided on the same side of the sensor substance.In a method according to the invention, a determination may be made as to whether an analyte is present in a sample. Such a method may provide a sensor, such as that described above. Electromagnetic energy may be provided to the sensor substance using the energy source, and the sensor substance may be contacted with a sample. Electromagnetic energy may be emitted from the sensor substance and received at the detector. The detector may provide a signal indicating the type of electromagnetic energy emitted from the sensor substance. The signal from the detector may be analyzed to determine whether the analyte was detected.
    • 传感器具有传感器物质,电磁能源和检测器。 当感兴趣的分析物与传感器物质接触并且电磁能量被传感器物质接收时,传感器物质可能能够发射不同于由能量源提供的电磁能量的电磁能量。 能量源和检测器可以设置在传感器物质的同一侧。 在根据本发明的方法中,可以确定样品中是否存在分析物。 这种方法可以提供如上所述的传感器。 可以使用能量源将电磁能量提供给传感器物质,并且传感器物质可以与样品接触。 电磁能量可以从传感器物质发射并在检测器处接收。 检测器可以提供指示从传感器物质发射的电磁能量的类型的信号。 可以分析来自检测器的信号以确定是否检测到分析物。
