ABSTRACT
Aim To establish the rapidly detecting method of glucose concentration in brain microdialysate.Method Using high-performance liquid chromatography (HPLC) with electrochemical detector (ED) and Nano-Copper screen-printed electrode (NCSE100)-Flow injection analysis the glucose concentration in brain microdialysate were detected.Result The related coefficient (r) of glucose standard curve was 0.9995. The variation coefficient (CV) within a day was 4%~7%. The striatum extracellular glucose concentration in rats was(2.4?0.8) mmol?L-1. These results indicated that our method was reliable.Conclusion Using HPLC with ED, NCSE100, and flow injection analysis the glucose concentration in brain microdialysate were detected, which has certain applied worth.
