“…The effects of other interfering species existing in the biological system were tested using an amperometric method to verify the selectivity of AgNPs-rGO/SPCE for the detection of DA and 5-HT. A concentration of 100 μM of serotonin, dopamine, uric acid, ascorbic acid, glucose, Na + and K + are successively added to the electrochemical cell under stirring at periodic intervals and at fixed potential of 0.35 V. 1 As illustrated in Fig. 6C, the current response was dominated by DA and 5-HT compared with other interfering species, demonstrating the effective selectivity of AgNPs-rGO/ SPCE for the concurrent detection of both biomolecules.…”

“…Serotonin (5-HT) and dopamine (DA) are two important neurotransmitters involved in the transmission of messages between the brain and the body, and in the regulation of physiological and behavioral functions. [1][2][3] Abnormal levels of these biomolecules can cause symptoms associated with several diseases, including cardiovascular disease, 4,5 schizophrenia, 6 Alzheimer's, 7 and Parkinson's disease. 8 In addition, research has revealed their involvement in the progression of several cancers, such as breast, 9,10 lung, 11 gastric, 12 ovarian, 13 and liver cancer.…”

An electrochemical sensor based on eco-friendly green synthesized silver nanoparticles decorated reduced graphene oxide (AgNPs-rGO) modified screen-printed carbon electrode (SPCE) for the simultaneous detection of serotonin (5-HT) and dopamine (DA) is reported for the first time. The experimental parameters affecting the sensor performance were optimized in terms of AgNPs-rGO coating amount, scan rate and electrolyte pH (6-8). Under optimal conditions, the AgNPs-rGO/SPCE was employed to individually determine both analytes using DPV technique. The sensor was also efficient in the simultaneous detection of these species and reported well-resolved oxidation peaks with a linear range of 10-100 μM and detection limits of 7 µM and 7.41 µM, respectively. The developed device showed good selectivity, reproducibility, and repeatability. Furthermore, it was successfully applied to the determination of both biomolecules in artificial urine samples with good recovery. The main advantages of the designed sensor are its simplicity, portability, and low cost.

“…The polyCU-modified PGE presented a higher electrocatalytic response towards hydroxylamine in comparison to the bare PGE [162]. Nayak et al [163] discussed the cyclic voltammetric CU accumulation onto GCE bare and modified with various carbon-based materials (CNTs, oCNTs, graphite, and GO) and presented the mechanism for CU electrodeposition and the analytical performances of a polyCU-oCNTs/GCE for the simultaneous sensing of dopamine and serotonin. Dinesh et al [164] reported the electrodeposition of a CU-quinone derivative at a CB/GCE by in situ electro-oxidation via CV in KCl-HCl pH 2.00 solution.…”

Curcumin (CU) is a polyphenolic compound extracted from turmeric, a well-known dietary spice. Since it has been shown that CU exerts beneficial effects on human health, interest has increased in its use but also in its analysis in different matrices. CU has an antioxidant character and is electroactive due to the presence of phenolic groups in its molecule. This paper reviews the data reported in the literature regarding the use of electrochemical techniques for the assessment of CU antioxidant activity and the investigation of the voltammetric behavior at different electrodes of free or loaded CU on various carriers. The performance characteristics and the analytical applications of the electrochemical methods developed for CU analysis are compared and critically discussed. Examples of voltammetric investigations of CU interaction with different metallic ions or of CU or CU complexes with DNA as well as the CU applications as electrode modifiers for the enhanced detection of various chemical species are also shown.

“…The response for the analyte on the bare glassy carbon electrode is very poor and the presence of other bioactive molecules within the similar potential range may interfere with the signal. 9 Hence, the modification of bare electrode with nanoparticles, 10 carbon nanotubes, 11,12 carbon nanofibers, 13 carbon quantum dots, 14 metals, metal oxides, 15 graphene based materials 16 and polymers 17,18 are essential. Recently metal organic frameworks (MOFs) are given more attention owing to their large surface area, high porous nature and tunable structures, making them attractive for a wide range of applications, including gas storage, super capacitors, 19 separation, oxygen and hydrogen evolution 20,21 catalysis, 22 sensing, 23 water treatment, 24 drug delivery 25 and more.…”

Nanosheet like nickel metal organic frameworks (Ni-MOFs) have been synthesized using solvothermal route at room temperature. Functionalized multi-walled carbon nanotubes (MWCNTs) have been embedded into these MOFs through equilibration to prepare the composite. The composite (Ni-MOFs/MWCNTs) has been used as a modifier in sensor fabrication on a glassy carbon electrode surface and successfully applied in dopamine measurement through cyclic voltammetry and square wave voltammetry techniques. The composite has exhibited enhanced electrochemical performance with a very low detection limit of 0.017 µM. The protocol showed wide linearity in the concentration range 2 – 200 µM with a sensitivity of 17.14 µAµM-1cm-2. The proposed electrochemical platform exhibited high sensitivity and selectivity in dopamine sensing which has been successfully applied to real sample matrices like human blood serum and injection.
