    摘要:

    重金属离子是水污染的主要污染物之一,即使微量的重金属离子也会对生态环境和生物造成危害。 水体中的重金属离 子通过食物链在人体中积累,汗液、血清等体液中的重金属离子可作为特定疾病的标志物。 实现液体样本中重金属离子的快 速、灵敏检测,对生态环境监管和精准医疗具有重要意义。 首先介绍了基于微机电系统(MEMS)技术的重金属离子传感器,包 括紫外-可见分光光度法、比色法、荧光检测法、发光化学法、电化学法和悬臂梁式检测方法。 其次论述了与上述检测方法匹配 的便携式仪器,最后对未来重金属离子检测传感器与系统的发展趋势和应用前景进行了展望。

    Abstract:

    One of the main contributors to water pollution is heavy metal ions, which is dangerous for both human health and the environment even in tiny amounts. Heavy metal ions have been discovered to be biomarkers for several diseases and pathological situations in bodily fluids like sweat and serum. Therefore, in ecological environmental supervision and precision medicine, the quick and accurate detection of heavy metal ions plays a critical early warning role. This article firstly compares the widely used detection methods at present and then summarizes the heavy metal ion sensors developed based on MEMS technology, which can be divided into UV-visible spectrophotometry, colorimetry, fluorescence detection, luminescent chemistry, electrochemical method, and cantilever beam detection method according to the detection principle. Based on the aforementioned detection methods, the present portable instruments and systems developed are summarized, and the development trend and application prospect of heavy metal ion detection sensors and systems.
