Abstract:
      Pesticide residue is one of the main risk factors affecting food safety. Traditional methods for the determination of pesticide residue require costly and large-scale equipments, which can't meet the needs of on-site and real-time detection. In recent years, with the development of the preparation and functionalization technologies, nanomaterials have been extensively studied for the determination of pesticide residue. Various nanosensors were fabricated by combination of nanomaterials with fluorescence, colorimetric, surface-enhanced Raman scattering and electrochemical method, which enhanced the specificity and senditvity largely, and achieved a breakthrough of rapid detection technology. Herein, the research progress on application of four main types of nanosensors for rapid detection of pesticide residue is reviewed, and the prospects are discussed. The fabrication of portable nanosensor with high selectivity, excellent anti-interference ability and broad application prospect will continue to be a main research focus.
