Sensing performances of spinel ferrites MFe2O4 (M = Mg, Ni, Co, Mn, Cu and Zn) based electrochemical sensors: A review

) to create differentiated voltammetric sensors. The association of these materials with graphene, glassy carbon, carbon nitride, ionic liquids, nanoparticles of noble metals, oxides of transition metals and other materials can produce notable synergic responses towards electrochemical activity. Some of these sensors can produce very sensitive signals and ample concentration ranges for compounds such hydrogen peroxide, glucose and bisphenol A, and present potential for many other applications. Along this review, all these aspects will be discussed and the main results are organized in tables, using as a base the metal associated with the ferrite.
