Abstract: In this work, a new molecular imprinted sensor based on polyoxometalate (H3PW12O40, POM) functionalized carbon nitride nanotubes (C3N4 NTs) nanocomposite was prepared for bilirubin (BR) analysis. The structures of prepared surfaces based on the nanocomposite were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray photoelectron spectroscopy (XPS) and energy dispersive x-ray analysis (EDX). After that, BR imprinted electrode on H3PW12O40/C3N4 NTs nanocomposite was developed by cyclic voltammetry (CV) in 100mM pyrrole containing 25mM BR. The linearity range and the detection limit of the developed method were calculated as 1.0 x 10-12 - 1.0 x 10-10 M and 3.0 x 10-13 M, respectively. In addition, the imprinted sensor was applied to human plasma samples with high recovery and selectivity
