Evaluating Ternary Metal Oxide (TMO) core-shell nanocomposites for the rapid determination of the anti-neoplastic drug Chlorambucil (Leukeran™) by electrochemical approaches.

A functional ternary nanocomposite (MnO2@NiFe2O4) with hierarchically grown flower-like core-shell assembly has been prepared through a simple two-step hydrothermal methodology. The crystallographic information of the sample was obtained via X-ray diffraction. The morphological details of spherical NiFe2O4 (core) and flower-like MnO2 (shell) were examined over FE-SEM and TEM; finally, the XPS confirms the successful formation of MnO2@NiFe2O4 ternary nanocomposite. The surface area of finely grown hierarchical MnO2 flowers on NiFe2O4 nanoparticles was measured through BET isothermal studies. The ternary nanocomposite was employed for the specific and sensitive detection of anticancer drug Chlorambucil. Under the well-optimized condition, the graphically plotted calibration curve was attained at MnO2@NiFe2O4/GCE towards the detection of anticancer drug Chlorambucil, which possesses the wider linear range of 0.025-574.5 μM, with the minimal detection limit of 4.68 nM. The feasibility of the sensitive layer has also been inspected on the pharmaceutical sample (oral tablets) and the biological matrix (human urine), whereas the appreciable spike recoveries were obtained.
