CRISPR is an adaptive immune defense system found in bacteria and archaea that is resistant to heterologous invasive genetic material. Later studies showed that the CRISPR system can be used for gene-editing. This study used the Web of Science database as a search object, then visually analyzed the literature related to CRISPR gene-editing technology with CiteSpace IV. The results show that publications had increased year by year. USA ranked first in terms of publications. China is second, but the centrality is very low. Doudna JA and Zhang F have made outstanding contributions. There are close connections between the internal institutions of the various states, but there are few links between the states. The hot spot and frontier are the application of CRISPR in animals, plants, detection, diagnosis, and clinical treatment.
