Abstract

Biosensor is immobilized biosensitive material as identification element, which has the characteristics of small size, high specificity, fast response and high accuracy, possessing a broad market application prospect. In recent years, biosensor technology has developed rapidly, and research achievements have emerged continuously. In order to better understand the research status of China’s biosensor industry and further promote its healthy development, based on the IncoPat patent database, ITGinsight is used as a literature analysis tool. The overall research situation, regional layout, technical composition and research hotspots in the field of internal biosensors are analyzed, and the core patents are identified. The results show that although China ranks first in the world in the number of biosensor patents, there are problems such as unbalanced regional distribution of scientific research strength, weak research and development strength of enterprises, and inadequate mastery of key core technologies. Finally, corresponding countermeasures are put forward according to the shortcomings of biosensor research in China, which can provide reference for the rapid development strategy of biosensor technology in China.
