Preparation of cerium oxide–MWCNTs nanocomposite bulk modified carbon ceramic electrode: a sensitive sensor for tamoxifen determination in human serum samples

In this study, cerium oxide and multi-walled carbon nanotubes nanocomposite were incorporated into the ceramic electrode (CeO2–MWCNTs/CCE) as a renewable for electrocatalytic purposes. To demonstrate capability of fabricated electrode, determination tamoxifen an important anticancer drug with differential pulse voltammetry technique was evaluated in details. Linear range, limit detection sensitivity developed sensor found to be 0.2–40 nM, 0.132 nM 1.478 µA nM?1 cm?2, respectively. Ease production, low cost high electron transfer rate CeO2–MWCNTs/CCE promises it novel electro-analytical tool species real samples.
