Graphene is one of the promising hydrophobic carbon-based nanomaterials used for electrode modification in electrochemical sensor. However, hydrophobicity of graphene makes it incompatible with aqueous electrolyte solution, leading to significant impediment to the electron transfer process. Here, we aim to alter graphene property to be hydrophilicity by using an electrochemically reduced micellar...
The simultaneous determination of two pesticides, namely isoproturon and carbendazim, by single drop analysis using a graphene-based electrochemical sensor with square wave stripping voltammetry was developed. A 60μL aliquot of the test sample was applied onto the sensor and analyzed, where clear electro-oxidation peaks from the isoproturon and carbendazim were detected. After the assay conditions...
