Metal–organic framework for the extraction and detection of pesticides from food commodities

Abstract

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.

Sensor Array Chip for Real‐Time Field Detection and Discrimination of Organophosphorus Neurotoxins

“…Additionally, OP pesticides present global threats through contamination of the agricultural supply chain [3,4] . Real‐time detection and discrimination of CWA threats, like V‐type nerve agents (NAs) [5,6] and G‐type NAs, [3,7–12] in the presence of OP pesticides, [4,13–19] are thus essential for initiating timely and efficient countermeasures [20–27] . However, the simultaneous detection of OP threats in their complex mixtures, comprising OP NAs, OP pesticides, and non‐OP chemical pollutants, has not yet been investigated.…”

“…[3,4] Real-time detection and discrimination of CWA threats, like V-type nerve agents (NAs) [5,6] and G-type NAs, [3,[7][8][9][10][11][12] in the presence of OP pesticides, [4,[13][14][15][16][17][18][19] are thus essential for initiating timely and efficient countermeasures. [20][21][22][23][24][25][26][27] However, the simultaneous detection of OP threats in their complex mixtures, comprising OP NAs, OP pesticides, and non-OP chemical pollutants, has not yet been investigated. Achieving such discrimination presents a major challenge for realizing reliable and rapid field detection of OP threats.…”

Metal–Organic Frameworks in Agriculture

“…In particular, related to agrochemicals, MOFs have been proposed (i) in water remediation through the elimination (adsorption/degradation) of agrochemicals or derived products, (ii) as carriers for the controlled release of agrochemicals, and (iii) as sensors for the determination of these molecules in water or food (Figure ). While not many reviews have detailed the use of MOFs in the elimination of agrochemicals as contaminants in water − or their potential in the detection and quantification of these potentially toxic molecules, ,, the use of MOFs as agrochemical delivery systems is a very recent research field, initiated in 2015 . Grouped by their function, this Review will discuss the MOFs and MOF-based composites that have been investigated to date in the agricultural domain.…”

Nanostructured materials for glyphosate capture—A mini-review

“…In recent years, nanoscience and nanotechnology have positioned themselves as two concepts of great relevance in the world. Nanotechnology has gained great strength in the scientific world, the ability to handle the matter on a nanometric scale has opened the possibility of obtaining nanomaterials in the form of metals, ceramics, polymeric materials, or composite materials, with increasingly specific properties, capable of supplying a large number of technological and industrial needs (Kumar et al, 2018;Saleh, 2020;Mazari et al, 2021;Xu et al, 2021). Within a large number of applications of nanomaterials, the removal of contaminants is an area in which they are currently being widely used, taking advantage of their properties and versatility.…”
