丝网印刷技术在纸基传感器中的应用OA北大核心CSTPCD

With the advances of science and technology,the research on paper-based sensors has progressed rapidly and their applications continue to expand.Paper microfluidics and paper-based flexible electronics have become two important development directions for paper-based sensors.Meanwhile,screen printing technology,which has advantages such as low cost,fast screen making,easy printing,and wide applicability,has been extensively used in the fabrication of paper-based sensors.This paper provided a brief overview of the development of paper-based sensors,and discussed the research progress in recent years of fabricating paper-based chemical sensors and biosensors based on screen printing technology from three aspects:constructing hydrophobic walls to prepare paper-based microfluidic channels,depositing functional reagents,and printing paper-based electrodes to prepare paper-based electrochemical sensors.In addition,the research progress of paper-based physical sensors based on screen printing technology was described.Finally,challenges and development directions for future applications of screen printing in paper-based sensors were discussed.
