Noble metal nanoparticles are emerging as important materials among the rapidly expanding domains with potential applications in many fields. In this work Ruthenium nanoparticles (RuNP) have been synthesized by a green synthetic pathway using citric acid as the reducing agent and curcumin as the stabilizing agent. The synthesized nanoparticles have been characterised by SEM, XRD and UV-vis spectroscopy. The nanoparticles have been used as an electrocatalyst for the determination of Hydrogen peroxide (H2O2). The RuNP modified electrode response under hydrodynamic conditions has been studied using various voltammetric techniques. The electrode shows a good response towards electrocatalytic reduction of H2O2 with a linear range from 1.66 ?M to 54.70 ?M. The utility of the sensor for real sample analysis has been evaluated by carrying out analysis of different milk samples and the results obtained were found to be satisfactory. The work demonstrates that the new RuNP modified electrode is a promising tool for detection of important analytes.
