Background: The mycophenolate mofetil is an immunosuppressant drug with wide application
in the treatment of cancer and prevent rejection in organ transplantation. This drug showed many
sides effects for pregnant women and determination of this drug is very important in the human body.
Objective: A new electrochemical strategy was described for analysis of Mycophenolate Mofetil
(MMF) using novel voltammetric sensor. The sensor was fabricated using NiO/SWCNTs and 1-methyl-
3-butylimidazolium bromide as two conductive mediators for modification of carbon paste electrode
(NiO/SWCNTs/MBBr/CPE). The NiO/SWCNTs/MBBr/CPE can be used for analysis of MMF in
aqueous buffer solution in the concentration range of 0.08-900 µM. In addition, the NiO/SWCNTs/
MBBr/CPE reduced oxidation over-potential of MMF ~ 80 mV and increased the oxidation current of
MMF ~ 2.85 times. In the final step, NiO/SWCNTs/MBBr/CPE was used for determination of MMF in
pharmaceutical serum and tablet samples.
Keywords: NiO/SWCNTs, mycophenolate mofetil, 1-methyl-3-butylimidazolium bromide, electrochemical analysis, drug samples,
