Abstract

A greatly selective, and sensitive 3,4-Dihydroxy-trans-cinnamate sensor based on a poly (sodium 4-styrenesulfonate) (PSSS) coated with functionalized multiwalled carbon nanotubes (PSSS@f-MWCNTs) composite modified electrode was improved. The fabricated PSSS@f-MWCNTs/GCE displayed an excellent voltammetric response for caffeic acid to compared control electrodes. Under optimum conditions, the modified electrode showed a wide linear range at caffeic acid concentrations of 0.4-173.9 μM. The limit of detection is 35 nM and sensitivity is 17.44 μA μM^-1cm^-2. The improved sensor method was showed good anti-interference, reproducibility, good repeatability, and excellent storage stability.
