Polymers and metal oxides are well-known materials for various electrochemical sensing applications due to their distinctive properties. In the current decades, the use of composites and nanocomposites of polymer and/or metal oxide in the sensing domain has been drastically explored. This review conveys the pursuance of several conducting and non-conducting polymers such as polypyrrole, polyvinylpyrrolidone, polyaniline, polythiophene, polyacetylene and their derivatives with several metal oxides (such as TiO 2 , SiO 2 , CeO 2 , ZnO, CuO, MnO 2 , Fe 3 O 4 ) in the area of electrochemical sensing of some important biomolecules. Herein, various methods of synthesis of nanocomposites, different characterization techniques employed, electrode modification and fabrication methods adopted are cited with rich comparative discussion for sensing applications, specifically in the field of electrochemical and bio-sensing impact using various electrochemical methods are also reviewed. The review will provoke and support the modern researchers of the field to approach new avenues.
