Simultaneous and sensitive detection of dopamine and uric acid based on cobalt oxide-decorated graphene oxide composite

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

“…To solve this problem, different modified electrodes based on the carbon nanomaterials, metal nanoparticles, composites, polymers, and metal oxides have been provided to determine the dopamine [18][19][20]. Recently some nanocomposites containing metal oxides such as CuTRZMoO 4 @PPyÀ n [21], Co 3 O 4 /GO [22], AuÀ ZnO NCAs [23] and TiO 2 À WO 3 [24] have been used for electrochemical determination of DA . In addition, binary transition-metal oxides (BTMOs) due to their superior properties such as better resistance to deactivation, high catalytic activity, and good selectivity have been used in modification of electrodes [25].…”

A review of electrochemical impedance spectroscopy for bioanalytical sensors

“…That is, when researchers design electrode materials, EIS is used at each step of the electrode construction process to conrm successful immobilisation of electrode modications. Literature reports that use EIS only in this way have been discounted from this section (there are several examples of this that were ltered from this review from 2021 and 2020 7,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] ). Instead, this section seeks to present literature reports of EIS when used as the technique of choice for generating a quantitative analytical signal.…”

La(OH)3 Multi-Walled Carbon Nanotube/Carbon Paste-Based Sensing Approach for the Detection of Uric Acid—A Product of Environmentally Stressed Cells

“…Non-expensive and robust non-enzymatic sensors perform direct oxidation of UA on the surface of the electrode material [ 29 , 30 ]. Various materials, such as covalent organic and metal incorporated conductive polymers [ 13 , 16 , 19 , 23 ], metal oxides [ 30 , 31 , 32 ], carbon-based materials, and their composites [ 11 , 12 , 33 ], have been tested for UA detection [ 5 , 26 ]. These nanomaterials have been recognized as promising materials for the development of analytical methods for the detection not only of UA but also of numerous other biologically active compounds [ 34 , 35 , 36 , 37 ].…”
