Abstract:In order to gain a comprehensive and in-depth understanding of the current situation and development trends of immunodetection technology research field for pesticide residues in China，CiteSpace metrology software was used to visually analyze 810 pieces of relevant literature from 2001 to 2024 in China National Knowledge Infrastructure （CNKI） database about the number of published papers，authors，publishing institutions，keywords，etc. The results showed that the number of literature in the field of immunodetection technology for pesticide residues exhibited a rising trend. Sun Yuanming，Zhu Guonian，and others were the core members of China′s immunodetection technology for pesticide residues. Nanjing Agricultural University，Chinese Academy of Agricultural Sciences，other universities，and other scientific research institutes were the main research institutions in this field. This field mainly focused on four fields：the preparation of antigen and antibody，the immune expression，material labelling，and detection. The research progress in this field was divided into four stages：the first stage mainly focused on the design of pesticide hapten，as well as the preparation，purification，and identification of artificial antigen；the second stage focused on the research and development of immunochromatographic technology （ICT） combining specific antigen-antibody immune reaction and chromatographic separation technology；the third stage focused on the development of labeling materials from colloidal gold to magnetic nanoparticles，fluorescent microspheres，fluorescent latex particles，and so on；the fourth stage was mainly the integration of ICT and image recognition technology，big data，and internet of things technology.According to the emergence diagram and timeline diagram，the path of ′ICT，material labeling，and big data′could be used as a research hotspot and frontier in this field.
