Fabrication of Electrochemical Sensor Modified with Porous Graphene for Determination of Trace Calycosin

This study provided a novel analytical method for detection of CYS, rapid identification of Radix Hedysari and Radix Astragali, and gave another way for the trace analysis of CYS in biological samples. Furthermore, it would also deepen the application of PG in the field of pharmaceutical analysis.Graphical AbstractIt is significant to establish a simple, fast and precise analytical method for analysis of calycosin content in herbal materials, herbal preparations and human blood with the minimum blood concentration to realize the quality control of Chinese medicine and the diagnosis of diseases. This study provided a novel analytical method for rapid evaluation of the quality of Radix Astragali, Radix Hedysari and the real-time trace analysis of calycosin in biological samples. It also demonstrated that porous graphene (PG) can be extensively applied in designing high performance electrochemical sensors for the drug analysis.
