In this paper, NiO nanoparticles were synthesized using cetyl trimethyl ammonium bromide (CTAB) and sodium dodecyl sulfate (SDS). The prepared NiO nanoparticles were applied for the preparation of modified carbon-paste electrodes (MCPE) for the electrochemical investigations of potassium ferrocynide K-4 [Fe(CN)(6)] and dopamine (DA). The MCPE prepared from CTAB-NiO nanoparticles demonstrated an enhanced sensing response for K-4 [Fe(CN)(6)] and DA as compared with those of the MCPE fabricated from SDS-NiO nanoparticles. The MCPE prepared from SDS/polyglycine/CTAB-NiO nanoparticles demonstrated a further enhanced peak current response and effectively analyzed simultaneously DA, Ascorbic acid (AA), Uric acid (UA) and Bisphenol-A (BPA).
