Recent developments in electrochemical sensors for detecting hydrazine with different modified electrodes

“…According to some studies, function of the modied electrodes is basically dependent on the modier features, which is utilized in the modication procedure. [43][44][45] In addition, adjustment of the electro-chemical sensor, which use the conductive mediators like nanomaterials, ionic liquid (IL), and conductive polymers can cause assessing the biological specimens and medicines at the nanomolar level.

Facile Green Synthesis of NiO/NiCo2O4 Nanocomposite as an Efficient Electrochemical Platform for Determination of Dopamine

“…Therefore, designing a highly selective and sensitive approach for the precise DA detection is essential. Various approaches have been employed for determination of DA, such as electrochemical sensors [3], surface-enhanced Raman spectroscopy [4], colorimetric biosensors [5], fluorescence [6] and UV-vis spectrophotometry [7]. Nevertheless, various problems like longer detection time, expensive equipment and complex pretreatment are associated with those approaches that cannot meet the present needs for sensitive and rapid DA determination.…”

Recent developments in voltammetric and amperometric sensors for cysteine detection

“…In fact, modifying the electrode surface results in a catalytic part and very little changes at the surface, these features specify the sensitivity of the measurements in electroanalytical utilizations. [29][30][31][32][33] In general, the modied surfaces lead to:…”
