Objective To analyze the scientific research status of medical biosensors in the world. Methods Papers related to medical
biosensors were retrieved from the Web of Science database. By analyzing the global research situation of medical biosensors using bibliometrics method, the overall status of the publications in the field was showed, and the world’s leading countries, institutions
and teams were identified. Further more, the participation of countries in international cooperation in this field was analyzed by social
network analysis. Results From 1990 to 2022, a total of 12520 scientific papers on medical biosensors were published worldwide.
More than 50% of papers were published from 2018 to 2022 (54.72%). Clinical application and technical improvement related words
were the high-frequency words. China ranked the first in the number of published papers (4070), with a compound annual growth
rate of 25.58% from 2012 to 2021. The number of published papers (2595) and the annual compound growth rate (10.53%) in the
U.S. were lower than those in China, but the average citation frequency of articles in the U.S. was higher than that in China (43.12 vs.
23.95). China and the U.S. are the center of international cooperation. The U.S. is slightly better than China in various quantitative
indicators of international cooperation. The number of publications of other countries was less than 1000, so as the international
cooperation. Among the top 20 institutions in the world in terms of publication volume (≥90 articles) , 6 are in China and 5 are in
the U.S. The number of papers published by the Chinese Academy of Sciences ranks first in the world. A total of 9 corresponding
authors who published more than 20 articles in the world, including 5 Chinese authors. Conclusion The scientific research in the
field of medical biosensors is active worldwide, and the research results have accumulated rapidly in the past five years. China
ranks first in the world in this field and has maintained a rapid growth in the past decade. Chinese scientific research institutions,
represented by the Chinese Academy of Sciences, which are active in their research. In this field, the number and growth rate of U.S.
publications are lower than that of China, but the influence of U.S. papers and the performance of international cooperation are
better than that of China, playing the role of bridge in global cooperation. Other countries’ publications in this field are relatively
limited and their influence is weak.
