This article reports a detailed report of the synthesis and depiction of iron oxide nanomaterials (FeONPs) and their electroanalytical application. Electrochemical examination of Guanine (GU) and Dopamine (DA) is performed by synthesized iron oxide nanoparticles modified with carbon paste electrode (CPE) using differential pulse voltammetry (DPV) and cyclic voltammetry (CV) techniques. Peak potential of GU along with DA at FeOMCPE are 0.76 and 0.14V respectively. A good linear response was obtained by CV of GU and DA, in the concentration ranges 10-70 and10-70 μM respectively and the LOD value for GU along with DA was observed to be 5.3 and 4.6 μM. The result shows that the FeOMCPE exhibited good analytical performance and high electro-catalytic activity of DA and GU.
