Voltammetric Detection of Catecholamine Metabolites Using Troger's Base Modified Electrode
Original language description
The advantage of surface modification of voltammetric sensor for determination of catecholamine metabolites such as vanillyl mandelic acid (VMA) and homovanillic acid (HVA) is discussed. The amino-substituted coumarin derivative of Troger's base was deposi-ted on a graphite screen-printed electrode (poly(CTB)/G/SPE) cycling the electrode potential between 0 and 1.2V in 5 mL CH2Cl2 containing 1x10(-3)molL(-1) tetrabutylammonium tetrafluoroborate and 20L 0.1molL(-1) HCl. The poly(CTB) functions as both a selective recognition and pre-concentrator agent for catecholamine metabolites. The high sensitivity of the voltammetric sensor coated by a poly(CTB) film toward VMA was achieved despite the high structural similarity between the two tested metabolites. We presume the voltammetric detection of these species is based on selective binding by a poly(CTB) film supported by its good adherence to the electrode substrate. The voltammetric signals of VMA were observable in the concentration range 10-100molL(-1) (LOD=0.2molL(-1)) and 20-60molL(-1) (LOD=10molL(-1)) in the model and synthethic urine samples, respectively.
