The Research Status and Hotspots of Photoelectrochemical Aptasensor: A Bibliometric Review Based on VOS Viewer

In recent years, photoelectrochemical aptasensor (PEC aptasensor) is more and more popular among researchers for its unique advantages. This bibliometric review was based on VOS Viewer to visually analyze articles related to PEC aptasensor published on the Web of Science Core Collection from 2000 to 2022. By analyzing the publishing trends of 720 documents, we found that in the past five years PEC aptasensor had developed rapidly. The visual analysis of the cooperative relationship between countries/regions, institutions and authors will help us to understand the research status in this field. China not only had the highest publication volumes, but was the most actively engaged in cooperation between other countries/regions, and had the closest cooperation with USA. Qingdao University of Science and Technology was the institution with the most published articles, while Nanjing University with the highest number of citations. Among many researchers, Wang Kun of Jiangsu University had the highest number of articles published. Through the analysis of author-keywords, it was concluded that signal amplification, heterojunction and antibiotic were the main research directions in this field. We hope that the results can provide new perspectives and helpful suggestions for PEC aptasensor to promote the future development of it.
