This is the Pre/post print version of the work. The definitive version is published in Colloids and Surfaces B: Biointerfaces, vol. 95, pp 186-194Edged plane pyrolytic graphite electrode (EPPGE) was modified with and without Prussian blue (PB) nanoparticles and polyaminobenzene sulphonated single-walled carbon nanotubes (SWCNTPABS) using the chemical deposition method. The electrodes were characterised using microscopy, spectroscopy and electrochemical techniques. Results showed that edged plane pyrolytic graphite-single-walled carbon nanotubes-prussian blue (EPPGE-SWCNT-PB) electrode gave the best dopamine (DA) current response, which increases with increasing PB layers. The catalytic rate constant of 1.69 × 105 mol-1 cm3 s-1, Tafel value of 112 mV dec-1, and limit of detection of DA (2.8 nM) were obtained. Dopamine could be simultaneously detected with ascorbic acid. The electrode was found to be electrochemically stable, reusable and can be used for the analysis of DA in real drug samples.enPrussian blue nanoparticlesDopamineElectrochemical impedance spectroscopyInterferencesAscorbic acidArticleAdekunle, A., Farah, A., Pillay, J., Ozoemena, K., Mamba, B., & Agboola, B.
