“…An intriguing combination of two supramolecular classes was reported by Yu et al,arenes to detect pesticides (Yu et al, 2020). These nanosheets were formed by fabricating a threedimensional MOF (based on cadmium metal nodes and calixarene-containing bridging ligands), followed by exfoliation to form the nanosheets.…”

The detection of pesticides in real-world environments is a high priority for a broad range of applications, including in areas of public health, environmental remediation, and agricultural sustainability. While many methods for pesticide detection currently exist, the use of supramolecular fluorescence-based methods has significant practical advantages. Herein, we will review the use of fluorescence-based pesticide detection methods, with a particular focus on supramolecular chemistry-based methods. Illustrative examples that show how such methods have achieved success in real-world environments are also included, as are areas highlighted for future research and development.

“…With I 538 /I 650 as ratiometric output, the LOD for 3-NPA was 15 µM. PH-responsive Zinc-based MOFs, [Zn 2 (tcpbp)(4,4′-bipy) 2 ]·2DMA·6H 2 O were also used for highly sensitive detection of 3-NPA [ 78 ]. The sensing mechanism is a proton-induced quenching effect.…”

Nanoscale Metal-Organic Frameworks as Fluorescence Sensors for Food Safety

et al. 2021

Food safety has attracted attention worldwide, and how to detect various kinds of hazardous substances in an efficient way has always been a focus. Metal-Organic Frameworks (MOFs) are a class of hybrid porous materials formed by organic ligand and metal ions. Nanoscale MOFs (NMOFs) exhibit great potential in serving as fluorescence sensors for food safety due to their superior properties including high accuracy, great stability, fast response, etc. In this review, we focus on the recent development of NMOFs sensing for food safety. Several typical methods of NMOFs synthesis are presented. NMOFs-based fluorescence sensors for contaminants and adulterants, such as antibiotics, food additives, ions and mycotoxin etc. are summarized, and the sensing mechanisms are also presented. We explore these challenges in detail and provide suggestions about how they may be surmounted. This review could help the exploration of NMOFs sensors in food related work.

“…Since the first work on chemical sensing using an open luminescent-MOF (Tb-BTC, BTC=1,3,5-benzenetricarboxylate) [97] based on the hypersensitive lanthanide transition towards fluoride detection, several Eu and Tb-MOFs have been extensively employed as unique platforms for sensing humidity [98], ions [99] and organics [100][101][102], as well as for detecting explosives as hazardous molecules [103] (see Figure 17).…”
