Voltammetric study of dopamine at tavaborole modified carbon paste electrode

From the last several decades, the origination of electrochemical sensors for neurotransmiters has dawned as a research desk of notable significance, that fascinated a massive attentiveness ascribed to its high selectivity, sensitivity and fast response. The current work was succeeded the advancement of electrochemical sensors for the detection of a neurotransmitter dopamine (DA) by the tavaborole drug modified carbon paste electrode (MCPE) by cyclic voltammetric (CV) and linear sweep voltammetric (LSV) techniques. Many different parameters was studied such as sweep rate, varied concentration, pH study, interference study and stability. The simultaneous investigation of DA in the existence of ascorbic acid (AA) and uric acid (UA) was studied. The limit of detection (LOD) and limit of quantification (LOQ) was calculated. This method was successfully applied for the investigation of DA in human blood serum and also in injection sample. Tavaborole drug modified electrode shows promising electrochemical sensing of DA.
