چکیده مقاله
Electrochemical enzymless sensors are attractive by researchers due to their advantages including low fabrication cost, good selectivity and high stability. Transition metal oxides are a suitable materials for preparation of enzymless creatinine sensors due to their ability in interaction with creatinine. The present paper is devoted to an electrochemical synthesis of iron oxide nanoparticles for preparation of an impedance-based enzymless creatinine sensors. The electrodeposition of iron oxide on the surface was carried out through a constant potential method. The morphology of the prepared surface was studied by Field emission scanning electron microscopy (FESEM). Electrochemical impedance spectroscopy (EIS) was used as impedimetric method for determination of creatinine in samples. The results of EIS indicated an increasing trend in value of charge transfer resistance (Rct) from 12.7 kΩ for 60 μM creatinine to 14.45 kΩ for 80 μM creatinine. The prepared sensor can be used in rapid detection of creatinine in real samples.
