“…The response peak current increased as the pH changed from 5.0 to 7.0, and the highest peak current was observed at pH 7.0. A sharp decrease in peak current was then observed at higher pH values from 7.0 to 9.0, which was due to the instability of BM in the alkaline media [ 40 ]. Therefore, a buffer solution with a pH of 7.0 was chosen for further electrochemical detection.…”

In this work, a two-dimensional leaf-like framework-L embedded electrochemically reduced graphene oxide (ERGO@ZIF-L) was proposed as an outstanding electrode material for the sensitive electrochemical sensing of benomyl (BM). ZIF-L is surrounded by ERGO, which could effectively ensure the stability and dispersion of ZIF-L. With this unique combination, the prepared ERGO@ZIF-L displayed excellent synergistic characteristics with a large surface area, excellent conductivity, plentiful active sites, and high electrocatalytic properties, thus endowing it with high sensitivity for BM determination. The experimental parameters, such as solution pH, material volume, and accumulation time, were optimized. Under optimal conditions, the BM sensor showed a wide linear range (0.009–10.0 μM) and low-limit detection (3.0 nM). Moreover, the sensor displayed excellent stability, repeatability, and reproducibility, and good anti-interference capability. The method was successfully applied to detect BM in real-world samples.

Food safety as a public health issue has aroused worldwide concern. Food safety risks caused by the existence of food safety hazards in food may occur in all stages of the food supply chain. Thus, great emphasis is placed on sensitive, selective, and convenient analytical methods of various food safety hazards in food. At present, nanomaterials are at the forefront of various electrochemical sensing applications. Given their unique physical, chemical, and biological characteristics, nanomaterials are considered perfect candidates for the design of electrode surface to construct electrochemical sensors with excellent analytical performance. With the assistance of nanomaterials, electrochemical sensors are a potential alternative to conventional methods of food safety analysis. This review focuses on current research achievements of nanomaterial‐assisted electrochemical sensors for food safety analysis reported in recent 5 years. It highlights the different detection mechanisms for analytes, flexible sensing strategies based on nanomaterials, and portable miniaturized electrochemical devices. Finally, the challenges and limitations in the design of electrochemical sensors for food safety analysis are also discussed.

Recently, there is a growing demand in sustainable phytopathogens control research. Nanotechnology provides several tools such as new pesticides formulations, antibacterial nanomaterials and smart delivery systems. Metal nano-oxides and different biopolymers have been exploited in order to develop nanopesticides which can offer a targeted solution minimizing side effects on environment and human health. This work proposed a nanotechnological approach to obtain a new formulation of systemic fungicide fosetyl-Al employing ultrasonication assisted production of water dispersible nanocrystals. Moreover, chitosan was applicated as a coating agent aiming a synergistic antimicrobial effect between biopolymer and fungicide. Fosetyl-Al nanocrystals have been characterized by morphological and physical-chemical analysis. Nanotoxicological investigation was carried out on human keratinocytes cells through cells viability test and ultrastructural analysis. In vitro planktonic growth, biofilm production and agar dilution assays have been conducted on two Xylella fastidiosa subspecies. Fosetyl-Al nanocrystals resulted very stable over time and less toxic respect to conventional formulation. Finally, chitosan-based fosetyl-Al nanocrystals showed an interesting antibacterial activity against Xylella fastidiosa subsp. pauca and Xylella fastidiosa subsp. fastidiosa.
