“…Oxidation products can be reduced electrochemically in the electrode surface and therefore an electrochemical signal directly proportional to the concentration of the phenolic compound is obtained when H 2 O 2 is present in excess. 40 Based on these results, it was possible to determine phenolic compounds using electroanalytical method developed. As the disposable biosensor allow good sensitivity and high-speed scanning, it was employed to determine phenolic compounds in wastewater from coffee washing (environmental sample), using the voltammetry square wave technique.…”

“…Hernandez et al. 48 reported the horseradish peroxidase enzymatic electrochemical detection of phenolic compounds such as phenol, p ‐aminophenol, p ‐chlorophenol, hydroquinone and pyroca‐techol at a detection limit of 60×10 −7 M. Kafi and Chen 49 developed a amperometric biosensor using horseradish‐peroxidase (HRP) and methylene blue (MB) with chitosan on Au‐modified TiO 2 nanotube arrays for the detection of p ‐nitrophenol and it was found that the detection limit of 9×10 −8 M in the linear range from 3×10 −7 to 1.2×10 −4 M. The comparison of the electrochemical detection of phenolic compounds of catechol, p ‐cresol and p ‐nitrophenol obtained in the presented study with the previous results reported in the literature is summarized in Table 1, showing that the proposed electrochemical sensor exhibited an excellent sensitivity with simultaneous sensing measurements towards catechol, p ‐cresol and p ‐nitrophenol. Moreover, the electrochemical method developed in this study for the simultaneous sensing of catechol, p ‐cresol and p ‐nitrophenol phenolic compounds possesses the advantages of a satisfied detection limit with high sensitivity, in conjunction with the electrode preparation method being very simple.…”

Owing to the high toxicity and detrimental effects of chemical contaminants to human health and the environment, public concerns over chemical contaminants in the environment and in foods have been mounting drastically. It is therefore significant to monitor contaminants via portable sensing devices, which encompass the demands of being low-cost and the potential for online environmental monitoring and food safety applications. This review will assess various concepts and recent advancements in design and the application of state-of-the-art nanomaterials through the incorporation of carbon nanomaterials, metallic and metallic oxide nanoparticles, titanium dioxide nanotubes, and dendrimers toward the development of electrochemical sensors for the detection of chemical contaminants in the environment and in foods. The development of nanomaterials based sensors facilitated by recent advances is having a major impact on sensor industries for environmental and food safety monitoring.Electrochemical sensing strategies have spurred intense interest in the research community as they have the capacity to serve as ideal sensor technology candidates, having such features as rapid response, robustness, high sensitivity and selectivity, low cost, miniaturization, and the potential for real-time monitoring. Nanomaterials have strong potential for increasing the competitiveness of new sensors for environmental monitoring and food safety applications through the combination of efficacious, yet simple fabrication techniques in the development of critical nanometric interfaces, and the optimization of their design and performance. Opportunities and future considerations for the use of nanomaterials in electrochemical sensors for producing advanced environmental and food sensing devices will also be addressed.
