The progress in modern agricultural practices could not have been realized without the large-scale contribution of assorted pesticides (e.g., organophosphates and nonorganophosphates). Precise tracking of these chemicals has become very important for safeguarding the environment and food resources owing to their very high toxicity. Hence, the development of sensitive and convenient sensors for the on-site detection of pesticides is imperative to overcome practical limitations encountered in conventional methodologies, which require skilled manpower at the expense of high cost and low portability. In this regard, the role of novel, advanced functional materials such as metal-organic frameworks (MOFs) has drawn great interest as an alternative for conventional sensory systems because of their numerous advantages over other nanomaterials. This review was organized to address the recent advances in applications of MOFs for sensing various pesticides because of their tailorable optical and electrical characteristics. It also provides in-depth comparison of the performance of MOFs with other nanomaterial sensing platforms. Further, we discuss the present challenges (e.g., potential bias due to instability under certain conditions, variations in the diffusion rate of the pesticide, chemical interferences, and the precise measurement of luminesce quenching) in developing robust and sensitive sensors by using tailored porosity, functionalities, and better framework stability.

“…Due to the structural resemblance of organophosphate pesticides (OPP) to the substrate (i.e., acetylcholine) of acetylcholinesterase (AChE), these pesticides cause a reversible inhibition of this enzyme since they take the place of the substrate at the level of the active site of the enzyme [5]. The QAs have a chemical structure similar to acetylcholine, such as OPP.…”

“…This is why it is necessary to develop innovative tools, such as biosensors that are sensitive, fast, inexpensive, portable, and even online, to set up more efficient self-monitoring, and thus better protect consumer health. Many biosensors based on the inhibition of enzymatic activity were built for the detection of organophosphate pesticides (OPP) [5][6][7][8]. These works draw inspiration for developing biosensors based on the use of enzymes as a recognition tool for the detection of disinfectant biocides.…”

Biocide disinfectants are used in agro-food industries in order to limit the development of pathogens present in environment or on surfaces in contact with food for human or animal consumption. Biocide residues remaining on food surfaces may constitute a toxicological risk for the consumer. Very little feedback from the field on the rates of biocide residues in the industry exist due to a lack of simple, fast and responsive self-checking methods. The development of biosensors for the detection of biocide disinfectants represents a promising way to explore this, but most of this research remains limited.
