Summary, etc. The role of functionalized nitrogen doped graphene (NGp) using poly(diallyldimethylammonium chloride) (PDDA) as modified electrode has been discussed. Pt-Pd bimetallic nanoparticles have been anchored on PDDA-NGp to form PtPd-PDDA-NGp nanocomposites, which are characterized by high resolution transmission electron microscope, X-ray diffraction and Raman spectroscopy. The simultaneous determination of paracetamol and tramadol has been carried out using the nitrogen doped graphene supported Pt-Pd nanoparticle modified glassy carbon electrode in 0.1 <em>M</em> Britton-Robinson buffer solution (pH 5.0). Two well-defined voltammetric peaks are obtained in square wave voltammogram measurements. It has been observed that the modified electrode can detect a wide linear range of concentrations of paracetamol from 5×10<sup>-6</sup> to 1×10<sup>-4</sup> <em>M</em>, and tramadol from 1.2×10<sup>-5</sup> to 2.4×10<sup>-4</sup> <em>M</em>. The limit of detection was found to be 1.8×10<sup>-7</sup> and 5.7×10<sup>-6</sup> <em>M</em> for paracetamol and tramadol, respectively (<em>S/N</em> = 3).
