ZnO Nanosheets-Decorated ERGO Layers: An Efficient Electrochemical Sensor for Non-Enzymatic Uric Acid Detection

Comparison of a 2D/3D imidazole-based MOF and its application as a non-enzymatic electrochemical sensor for the detection of uric acid

“…This form changes into the quinoid form after two nucleophilic additions of water. 44 Then the final product of allantoin was formed and supported by weakly acid, neutral, or slightly alkaline conditions of the aqueous medium. The mechanism is illustrated in Fig.…”

A review on 2D-ZnO nanostructure based biosensors: from materials to devices

“…Electrochemically reduced graphene oxide/ZnO nanocomposites grown on indium tin oxide electrodes have been reported for the detection of uric acid. 108 The linear response of the sensors was seen throughout a concentration range of 1 mM to 400 mM, and their sensitivity was 150.7 mA cm À2 mM À1 .…”

“…As a result, a highly sensitive and selective electrochemical biosensor is described for EP detection, with a linear response of 0.02 to 216 M, a LOD of 0.0093 M, and excellent estability (97.7% capacity retention after scanning for 20 h). Electrochemically reduced graphene oxide/ZnO nanocomposites grown on indium tin oxide electrodes have been reported for the detection of uric acid [108]. The linear response of the sensors was seen throughout a concentration range of 1 mM to 400 mM, and their sensitivity was 150.7 μAcm -2 mM -1 .…”

Selective non-enzymatic uric acid sensing in the presence of dopamine: electropolymerized poly-pyrrole modified with a reduced graphene oxide/PEDOT:PSS composite

“…17,18 Recently, several electrochemical sensors based on different platforms modified with poly-pyrrole have been employed to detect uric acid in real samples. [19][20][21][22][23][24][25] Previously, we have demonstrated the deposition of composite materials consisting of electrochemically reduced graphene oxide (ErGO) with a conductive polymer on a sensor electrode surface to give good electrochemical performance in uric acid sensing in the presence of dopamine as an interfering molecule. 26 It is well known that reduced graphene oxide materials exhibit exceptional mechanical, thermal, and electrical stability, combined with huge surface areas, which makes them useful as sensor electrode modifiers.…”
