Electropolymerized methylene blue on graphene oxide framework for the direct voltammetric detection of gallic acid

Buteinylated-hafnium oxide bionanoparticles for electrochemical sensing of wogonin

“…Interestingly, the mixed WG + GA sample showed a comparably high relative current percentage in line with pristine WG. This is due to the inherent oxidation potential of GA at +0.55 V. 53 It is worth mentioning that the interferent concentration tested in this study was ten-fold higher than that of the actual target WG.…”

Enzyme mimetic electrochemical sensor for salivary nitrite detection using copper chlorophyllin and carbon nanotubes-functionalized screen printed electrodes

“…4B). The heterogenous rate constant ( k s ) of the fabricated electrode was calculated using the Laviron equation as given below (eqn (5)), 46,47 where α is considered as 0.8 from the slope of the plot of the anodic peak current with the log of scan rate (Fig. S3, ESI†) 48 further from the slope of the plot of the anodic peak current with the square root of the scan rate (Fig.…”

Electrochemical Characterization of the Antioxidant Properties of Medicinal Plants and Products: A Review

“…Furthermore, chemical synthesis is usually multi-stepped (synthesis, cleaning, drying, and confirmation of the structure on each step) and requires the application of many reagents (some of them are toxic) and special equipment (Figure 15a). From this point of view, the electrochemical approach allows the obtaining of the final coverage via several or even one electrochemical step [147,153,158,169,173,175,176] (Figure 15b). As one can see from Table 5, the linear response for nanomolar and lower concentrations has been achieved for morin [153,155] and hyperin [160][161][162] using an appropriate electrode surface modifier.…”
