Fabrication a novel sensitive Au/ AuNPs, Polypyrole/ L-cystein/ Fe3O4@SiO2@NH2 sensor for application in Oxytocin and Epinephrine determination in biological fluids

In this study, a novel sensitive sensor is designed based on the Au/ AuNPs, Polypyrole/ L-cystein/ Fe3O4@SiO2@NH2 nano structure for monitoring ofOxytocin and Epinephrin (Adernalin) in human blood serum sample.Cyclic and square wave voltametry, Impedance spectroscopy and Scaning ElectronMicroscopy techniques are used to identify and verify the electrochemical behavior and characterization of the new modified electrode. The proposed sensor has goodsensitivity, selectivity, stability and long-term maintenance of electro activity and is used for applicationin Oxytocin and Epinephrine determination in biologicalfluids without any side interferences effects
