Abstract: Surface plasmon resonance (SPR) has been widely applied in various fields owing to its simplicity, low cost, no labeling, high selectivity, and real-time monitoring. SPR can be used not only for detecting analytes, but also determining kinetic parameters of molecular interactions. Interest in the development of SPR based immunosensors for the detection of low molecular weight pesticides in foods and environment has been rapidly increased over the last ten years. In this paper, the SPR principle and instrument types are briefly introduced. The category of recognized molecules immobilized on the SPR sensor surface, detection methods and their applications in pesticide detection are introduced emphatically. In addition, trends of SPR in the area of pesticide detection are also prospected.

Key words: surface plasmon resonance (SPR), sensor, pesticide, detection
