Direct Detection of Organic Species

4 Applications of ICPs in Electroanalysis 2.4.1 Direct Detection of Organic Species 

One of the most notable properties of ICP-modified electrodes lies in their capa-biUty to activate electrocatalytic redox processes it has been experimentally 

Quite interestingly, the occurrence of the current signal at significantly less positive potentials makes it possible achieve good resolution between oxidation peaks ascribable to different species in solution. Typical examples are given by the case of solutions containing ascorbic acid and either dopamine [55, 56] or uric acid 

Dopamine, epinephrine, catechol, serotonin, ascorbic acid PMTh [85] 

However, recalling the general comment already made for many electrode materials reported in this monograph, tests supporting the selectivity of the ICP coating are limited to only standard solutions or, at the most, to simple matrices
