Enzymless electrode is a device combines a material component and electrochemical transducer, used for the detection of an analyte. Nanomaterials are widely used in sen- sing areas due to its high positive effect on the response of enzymeless based electrode, it could be used as transduction element or immobilized onto the surface of electrochemical transducers, their presence increases sensitivities and gives a lower detection limits and enhance the kinetic performance of sensors. In this work, we report the effect of the most recent nonmaterial used for electrochemical detection, catalytic effect of various nanopar- ticles such as, nanomaterials, gold nanoparticles, conducting polymer, carbon nanotubes, and metal oxide immobilized on the surface of electrochemical transducers (platinum electrode, Carbon electrode and Gold electrode) is intensively analyzed. A comparative study of the nanoparticles effect on the analytical performance of sensor for the detection of phenolic compounds is also presented and discussed.
