The Global Research Trend in Electrochemical Microfluidic Technology: A Bibliometric Review

Electrochemical microfluidic technology has been extensively studied in many fields due to its significant advantages. Despite the increasing number of publications on the subject, there are no studies based on bibliometric analysis in this area. In this study, we performed a bibliometric analysis of 457 publications related to electrochemical microfluidic technology during 2012–2021 through the Web of Science core database. Results show that the hot topics include the development of label-free immunosensors, biosensors, microfluidic device performance, and low cost of equipment, and the major contributors to these publications are from China, USA, Spain, India, and Germany. In addition, applications of electrochemical microfluidics in biomedicine, food safety, and environmental monitoring are summarized and analyzed. Finally, the future challenges as well as strategies for future research are discussed. This bibliometric review will be useful for researchers in gaining new insights into the electrochemical microfluidic technology.
