In this study, a composite comprising a rare-earth metal, samarium vanadate (SmVO4, SmV), anchored to halloysite nanotube (HNT) 

making SmV/HNT nanocomposite is synthesized for the sensitive electrochemical determination of furaltadone (FLD) through differential

pulse voltammetry analysis based on the synergistic effect of SmV/HNT (the catalytic activity and chemical stability of SmV, which was

further boosted by the improved surface area and conductance of HNT). Further, in the microscopic studies, it is revealed that SmV 

exhibits a tetragonal zircon-type crystalline structure, with I41/amd (141) space group, whereas HNT comprises a multiphase kaolin 

composition as a gibbsite-like octahedral sheet with multivalency, and the morphological irregularities of the individual constituents are

rectified in the composite. The SmV/HNT composite is spray-coated on polyethylene terephthalate sheet, which delivered a promising

 trace level limit of detection (0.009 μM) over a wide working range (0.05– 194.4 μM) for FLD. Furthermore, real sample analysis

is performed using human serum, and pharmaceutical tablet and the results reveal exceptional repeatability and sensitivity, 

indicating the real-time application of SmV/HNT in the pharmaceutical domain.
