We will develop an integrated ultra-compact chemical sensor system that is suitable for ppb- to ppm-level detection of common contaminants in water and air. Initial targets are the heavy metal ions lead, Pb(II), and mercury, Hg(II) in groundwater and surface water. The same sensor platform will also be used for sensing of volatile organic compounds (VOCs) and initially we will focus on BTEX (benzene, toluene, ethylbenzene and xylene) as a contaminant class that is indicative of poor indoor air quality. In a departure from previously developed chemical sensor platforms we will use micro-photonic devices, in particular micron-sized interferometers and ring-resonators, as a versatile sensing platform.

我们将开发一种集成的超小型化学传感器系统，适用于水和空气中常见污染物的ppb至ppm级别的检测。最初的目标是地下水和地表水中的重金属离子铅、铅(II)和汞、汞(II)。同样的传感器平台也将用于挥发性有机化合物(VOCs)的传感，最初我们将重点关注BTEX(苯、甲苯、乙苯和二甲苯)作为指示室内空气质量较差的污染物类别。与以前开发的化学传感器平台不同，我们将使用微型光子器件，特别是微米尺寸的干涉仪和环形谐振器，作为多功能传感平台。
