“…For example, metal-organic frameworks (MOFs) have received a lot of attention in many different fields, including analytics, so it is not surprising that MOFs were also investigated for pesticide quantification. Karimian et al [ 149 ] applied TiO 2 -functionalized graphene oxide to modify MOF UiO-66 for the simultaneous determination of paraoxon and chlorpyrifos. Appreciable performances were observed, with LODs of 0.2 10 −3 μM (paraoxon) and 1.0 10 −3 μM (chlorpyrifos), and the corresponding linear ranges of 1.0–100.0 10 −3 μM and 5.0–300.0 10 −3 μM, respectively, with the use of square wave voltammetry.…”

Electrochemical sensors play a significant role in detecting chemical ions, molecules, and pathogens in water and other applications. These sensors are sensitive, portable, fast, inexpensive, and suitable for online and in-situ measurements compared to other methods. They can provide the detection for any compound that can undergo certain transformations within a potential window. It enables applications in multiple ion detection, mainly since these sensors are primarily non-specific. In this paper, we provide a survey of electrochemical sensors for the detection of water contaminants, i.e., pesticides, nitrate, nitrite, phosphorus, water hardeners, disinfectant, and other emergent contaminants (phenol, estrogen, gallic acid etc.). We focus on the influence of surface modification of the working electrodes by carbon nanomaterials, metallic nanostructures, imprinted polymers and evaluate the corresponding sensing performance. Especially for pesticides, which are challenging and need special care, we highlight biosensors, such as enzymatic sensors, immunobiosensor, aptasensors, and biomimetic sensors. We discuss the sensors’ overall performance, especially concerning real-sample performance and the capability for actual field application.

“…Karimian et al demonstrated the Zr-MOF with TiO 2 functionalized graphene oxide@UiO-66 (TGO@UiO-66) for simultaneous detection of paraoxon and chlorpyrifos. The square wave voltammogram (SWV) of TGO@UiO-66/GCE in presence of paraoxon and chlorpyrifos showed two characteristic peaks at 0.45 and 1.3 V. The designed sensor exhibited low detection limits of 0.2 and 1.0 × 10 -9 M within the linear ranges of 1 -100 × 10 -9 M and 5 -300 × 10 -9 M for paraoxon and chlorpyrifos [53]. Bhardwaj et al reported the three-phase composite material consisting of SiO 2 -coated Cu-MOF, single layer graphene, and aniline was synthesized.…”

Metal organic frameworks (MOFs) are a class of porous materials designed by coordination chemistry between metal ions and secondary organic building units (linkers). They emerged as an extensive class of crystalline materials with higher porosity than other framework materials like zeolites, activated carbon and metal-complex hydrides, respectively. Besides, they have high thermal stability, well-organized structure, low density, large internal surface area, ease in synthesis and broad-spectrum properties which makes them suitable for diverse applications. On the other hand, bulky structure of MOFs having some limitations like poor solubility, lacking electronic conductance and surface to volume ratio is minimal. To fulfill the above shortcoming is to introduce properties of other active materials like carbon nanostructure, metal oxide, metal nanoparticles, graphene carbon nitrite so on. Among the different composite materials especially carbon-based nanocomposite like graphene oxide (GO) and its derivatives have gained much attention because GO exhibiting 2D amphiphilic contains huge hydroxyl, epoxy and carboxylic acid functional groups on its conjugated planes.

Pesticide residues in food matrices, threatening the survival and development of humanity, is one of the critical challenges worldwide. Metal–organic frameworks (MOFs) possess excellent properties, which include excellent adsorption capacity, tailorable shape and size, hierarchical structure, numerous surface‐active sites, high specific surface areas, high chemical stabilities, and ease of modification and functionalization. These promising properties render MOFs as advantageous porous materials for the extraction and detection of pesticides in food samples. This review is based on a brief introduction of MOFs and highlights recent advances in pesticide extraction and detection through MOFs. Furthermore, the challenges and prospects in this field are also described.
