英文摘要:

      In recent years, the pollution of various kinds of heavy metal ions attracted a wide spread attention. The traditional monitoring system of heavy metal ions mainly depends on the professional equipment, which is expensive and time-consuming, the timeliness of on-site rapid detection is poor, and it is difficult to meet the needs of the current testing work. In view of the importance and urgency of the detection and analysis of heavy metal ions, it is of great practical significance to find simple, quick and public detection methods. With the rapid development of nanotechnology, nano sensors combined with optical, electrochemical, biological and material technologies have promoted the rapid development of the detection technology for heavy metal ion. This paper reviewed the research progress of nano sensors used in heavy metal detection in recent years, including nano optical sensors, nano electrochemical sensors and nano biosensors, and prospected the detection methods based on nano sensors, aiming to provide reference for the development of detection of heavy metal ions.
