“…70 The electropolymerization of a poly(sulfo-salicylic acid) lm on a gold electrode modied by 2-mercapto-benzothiazole selfassembled monolayer and MCNTs (PSSA/CNTs/MBT/Au) was performed by Arvand and co-workers. 71 Other researchers used their sensor to determine rutin ( Fig. 5) and the electrocatalytic activities of the resultant sensor toward rutin oxidation were ascribed to the presence of the PSSA/MWCNTs nanocomposite.…”

“…Likewise, Liu et al [ 22 ] employed a DPV method to study the simultaneous determination of myricetin and rutin on cMWCNT-pTh-Pt modified glassy carbon electrode(CGE), which obtained extremely satisfactory results with a 0.01–15 μM wide linear response range and the detection limits were 3 nM and 1.7 nM, respectively. In another study, the application of CNTs-based biosensor was proposed for the detection of rutin in orange, oat, salvia, and other real samples [ 23 ]. The results demonstrated that the sensor has high reproducibility and sensitivity.…”

Flavonoids have a variety of physiological activities such as anti-free radicals, regulating hormone levels, antibacterial factors, and anti-cancer factors, which are widely present in edible and medicinal plants. Real-time detection of flavonoids is a key step in the quality control of diverse matrices closely related to social, economic, and health issues. Traditional detection methods are time-consuming and require expensive equipment and complicated working conditions. Therefore, electrochemical sensors with high sensitivity and fast detection speed have aroused extensive research interest. Carbon nanomaterials are preferred material in improving the performance of electrochemical sensing. In this paper, we review the progress of electrochemical sensors based on carbon nanomaterials including carbon nanotubes, graphene, carbon and graphene quantum dots, mesoporous carbon, and carbon black for detecting flavonoids in food and drug homologous substances in the last four years. In addition, we look forward to the prospects and challenges of this research field.

“…There are many reports concerning polyphenol analysis with CNT-base electrodes. [13][14][15][16] In contrast, there has been only one report on curcumin sensing with CNT-based electrodes, 9 likely because of the hydrophobic nature of the CNT electrode and the fact that as-synthesised CNT is an agglomeration of molecules. In a previous study, we reported on an electrode with CNT-carboxymethyl cellulose (CMC) dispersion.…”

Electrochemical Detection of Curcumin in Food with a Carbon Nanotube- Carboxymethylcellulose Electrode

Herein, an electrochemical method is presented for the detection of curcumin in food using a carbon nanotube (CNT)carboxymethylcellulose (CMC) electrode. The CNT-CMC electrode exhibited ideal characteristics for curcumin detection, namely, a high response current and adequate peak separation toward curcumin oxidation. Cyclic voltammetry revealed two oxidation peaks. In the first scan, only the irreversible peak (Peak I) was observed at a higher potential. In the second scan, the reversible redox peak pairs (Peaks II and II′) appeared at lower potentials, and the potential of Peak I was decreased. Peak I corresponded to oxidation of the hydroxyl groups of the benzene ring to the catechol group via a phenoxy radical, while Peaks II and II′ indicated the redox loop system of the generated catechol group. The current at Peak II was used to quantify the concentration of curcumin in the linear range of 1-48 µM and detection limit of 0.084 µM. The concentrations of curcumin determined by the CNT-CMC electrode in real food samples were consistent with those determined by high-performance liquid chromatography.
