A novel nanocomposite with superior electrocatalytic activity: A magnetic property based ZnFe2O4 nanocubes embellished with reduced graphene oxide by facile ultrasonic approach

Herein, a novel Zinc Ferrite nanocubes (ZnFe2O4 NCs) decorated reduced graphene oxide (rGO) nanocomposite have been designed through a sonochemical method. After then, as-synthesized ZnFe2O4 NCs/rGO was characterized by XPS, XRD, HRTEM and EIS. Furthermore, the ZnFe2O4 NCs/rGO nanocomposite modified GCE (glassy carbon electrode) shows excellent electrochemical sensing performance towards biomarker of 4-nitroquinoline N-oxide (4-NQ) with fast detection. 4-NQ is one of the important cancer biomarker. Moreover, the fabricated sensor showed a wide linear window for 4-NQ between 0.025 and 534.12 μM and nanomolar detection limit (8.27 nM). Further, the as-prepared ZnFe2O4 NCs/rGO/GCE has been applied to the determination of 4-NQ in human blood and urine samples with excellent recovery results.
