An electrochemical sensing platform using Co/Ni-MOF materials was developed to measure dopamine after modification of SPCE. The Co/Ni-MOF materials demonstrate superior performance when combined with SPCE, yielding Co/Ni-MOF/SPCE with high electrocatalytic performance that enhances dopamine oxidation by reducing oxidation overpotentials and increasing peak current. The Co/Ni-MOF/SPCE sensor demonstrated a very low detection limit of 0.007 μmol L-1 and it could measure dopamine concentrations between 0.01 and 660.0 μmol L-1 through its linear detection capabilities. The Co/Ni-MOF/SPCE enabled researchers to identify DA and Tyr via DPV analysis because the method produced clear peak separation between the two compounds. The suggested approach has been successfully applied to measure DA and Tyr in real samples, which produced successful results.
