“…According to IUPAC criteria, the detection and quantification limits were 0.8 and 2.6 mg L -1 quercetin, respectively. This detection limit is not as low as most of the limits reported for other quercetin analysis methodologies [3,7,28,[30][31][32][33], however, the sensor proposed here is more advantageous because of its low cost and simple preparation. Moreover, the present detection limit is slightly lower than the limit reported by de Paula et al [23] (0.85 mg L -1 ) and quite lower than the reported by Jeevika et al [34] (2.03 mg L -1 ).…”

“…Thus, monitoring the amount of quercetin in these foods is important as a contribution to a healthier diet. Quercetin has been quantified by methods involving chromatography [2] and electrochemistry [3]. However, these methodologies can be expensive, time-consuming and require prior knowledge of equipment operation and data processing.…”

“…The mass transfer process occurring between the Ni-ZIF-8-S/GCE surface and the supporting electrolyte is in uenced by the electrolyte's pH value [32]. Thus, the effect of pH on the electrochemical behavior of quercetin at the Ni-ZIF-8-S/GCE was studied using cyclic voltammetry (CV).…”

“…On the Ni-ZIF-8-S/GCE, the average peak-to-peak separation (ΔEp) is measured as 36.8 mV. Using the formula 2.3RT/nF [32], the estimated electron transfer number (n) is calculated to be 1.60, suggesting that the electrochemical behavior of quercetin entails the transfer of two electrons and two protons. The proposed reaction mechanism can be depicted in Scheme 2.…”

At present, the electrochemical trace detection (picomole per liter level) with high sensitivity of quercetin is rare. In this work, the nickel-doped zinc-based zeolite imidazole framework with a four-point star morphology (Ni-ZIF-8-S) was successfully prepared by simple stirring and pH adjusting at room temperature. The strategies of nickel doping and morphology control endow Ni-ZIF-8-S with large specific surface area, unique hierarchical pore structure (micropores and mesopores), abundant active sites and excellent electron transport ability. Therefore, under optimal conditions, the electrochemical sensor based on Ni-ZIF-8-S can detect quercetin with a very high sensitivity of 622.0 µA µM− 1 and limit of detection is as low as 48 pM, which realizes ultrasensitive quantitative determination of quercetin in picomole per liter level. In addition, the proposed sensor also shows other excellent analytical performances, including good reproducibility, anti-interference and stability. As expected, the electrochemical sensor based on Ni-ZIF-8-S can perform quantitative detection of quercetin in complex real samples (urine) with acceptable results. The prepared sensor can be potentially applied in monitoring and quality control of quercetin.
