Ag nanoparticles anchored onto porous CuO nanobelts for the ultrasensitive electrochemical detection of dopamine in human serum

Graphene nanosheet-sandwiched platinum nanoparticles deposited on a graphite pencil electrode as an ultrasensitive sensor for dopamine

“… 10 This serious issue is addressed by electrode surface modification using various active electrochemical materials to achieve a well-resolved peak of dopamine. 13,14 The modified electrodes like MgO nanobelts/GCE, 15 Ag/CuO porous nanobelts, 16 Ni-MOF/GCE, 17 PA6/PAH-MWCNTs nanofibers/ITO, 18 biomass-derived porous graphene 19 , and flake shaped CuO nanoparticles/MCPE 20 were used for the sensing of dopamine.…”

Electrospun porous La–Sr–Co–Ni–O nanofibers for highly sensitive non-enzymatic glucose detection

“…Nanostructured metal oxides are considered as the most promising low-cost alternatives to the enzymatic and noble metal sensors for the selective detection of biomarkers. Several transition metal oxides are identified as suitable candidates for glucose [3][4][5][6][7] and dopamine [8][9][10] . The characteristics of the electrode surface are the primary factor that controls the electrochemical sensing of the above analytes.…”

Ultrasensitive and Selective Electrochemical Detection of Dopamine Based on CuO/PVA Nanocomposite-Modified GC Electrode

“…For instance, Reddy coworkers reported that CuO nanoparticles have sensor characteristics for determining dopamine electrochemically [3]. Furthermore, Li et al [4] reported Ag-doped CuO nanoparticles for the electrochemical determination of DA in human serum, Zhuang et al [5] synthesized Co 3 O 4 /CuO nanocage for dopamine biosensing, and Zou et al accounted for g-C3N4/CuO nanocomposites for the evaluation of dopamine [6].…”
