“…Electrocatalytic ability of the GCE/GRGO/[Co(bpy) 3 ] towards MP (5 μM) reduction was investigated in phosphate buffer (pH 7) and the corresponding voltammogram was given as Figure B. The first forward segment of the voltammogram displayed a sharp cathodic peak at –0.58 V, which can be manifested to the reduction of NO 2 –MP to NHOH–MP . In the backward segment, an oxidation peak is observed at –0.11 V for the oxidation of NHOH–MP to NO–MP, hence, this reaction is reversible and the corresponding reduction observed at –0.14 V during the second cycle.…”

“…The important sensor parameters, such as LOD and linear range were compared with previously reported modified electrodes and given as Table . According to the comparison table, various kinds of modified electrodes such us mesoporous carbon, carbon paste, metal nanoparticles, metal oxide, MWCNT, graphene oxide, MoS 2 and others used for the detection of MP . The analytical performance of the GRGO/[Co(bpy) 3 ] modified electrode is either superior or comparable to the previously reported electrodes.…”

“…An amperometric sensor based on modified glassy carbon electrode (GCE) showed excellent electrocatalytic activity towards reduction of H 2 O 2 , with a detection limit (LOD) of 0.83 μM, linear range of 5 µM–145 µM and sensitivity of 5.184 µA∙µM∙cm −2 . Direct reduction of methyl parathion (its nitro functional group) was reported [57]. Methyl parathion belongs to the group of organophosphorus pesticides which generate concerns in food safety, water management and public health.…”

“…Two dimensional materials such as MoS 2 and graphene are being extensively used in electrochemical biosensing due to their excellent electro-catalytic performance, ease of synthesis, high surface area, and tremendous physicochemical properties [16,17]. Govindasamy et al employed glassy carbon electrode modified with MoS 2 -graphene nanocomposite for sensitive amperometric determination of methyl parathion up to 3.2 nM concentration [18]. In another report, Govindasamy et al reported an electrochemical determination of chloramphenicol based on MoS 2 nanosheet-coated functionalized multiwalled carbon nanotubes (MWCNTs) hybrid.…”
