An Investigation of Methyl Viologen Functionalized Reduced Graphene Oxide: Chitosan as a Support for Pt Nanoparticles Towards Ethanol Electrooxidation

MnO2‐TiO2 Nanocomposite and 2‐(3,4‐Dihydroxyphenethyl) Isoindoline‐1,3‐Dione as an Electrochemical Platform for the Concurrent Determination of Cysteine, Tryptophan and Uric Acid

“…Unfortunately the direct oxidation of Cys on a bare electrode is hindered by relatively high over potentials, arising from the low electron transfer rates. Also Cys usually coexists with different electro‐active compounds including Trp and UA, which might have very close or similar oxidation peak potentials, and hence cause serious interfering effects and consequently the electrode materials can play important roles in electroanalytical methods and chemical modification of electrodes can be used as a means to overcome these problems . Various active materials, including e. g. nanocomposites, metal oxides, graphene and carbon nanotubes, and different mediators have recently been used to enhance electrodes .…”
