Research Situation Analysis of Magnetic SERS Detection Technology based on CiteSpace

Due to advantageous features such as sensitivity, specificity, ease of operation and rapidity, surface enhanced Raman spectroscopy (SERS) has emerged as one of the most promising analytical tools in recent years. Magnetic nanomaterials combined the unique properties and magnetism of noble metals together, and showed better performance as SERS substrate for detection of trace objects, so they were widely studied. Based on the WOS core database (1990-2020) used in SERS composite nanometer magnetic basement this field retrieved 805 records as the research object, using literature metrological visualization tools CiteSpace software, the magnetic nano basal core authors, institutions, and countries in the field of co-occurrence analysis and cited analysis, the article cited, highly cited analysis, keywords and science of clustering analysis, an analysis and a series of content were studied. The purpose of this study is to find the hot research topic and trend in the research field of SERS magnetic nano substrate technology for the detection of trace objects, and provides reference for the analysis of environmental pollutants.
