A comprehensive review on electrochemical and optical aptasensors for organophosphorus pesticides

A MnO2 nanosheet-mediated CRISPR/Cas12a system for the detection of organophosphorus pesticides in environmental water

“…[13][14][15] Therefore, to break the limitations, a great deal of effort has been invested in developing convenient and simple methods. [16][17][18][19][20][21] In this regard, low-cost, easy-to-use sensors are expected to find applications in OP detection.…”

Recent advancements in non-enzymatic electrochemical sensor development for the detection of organophosphorus pesticides in food and environment

“…Consequently, it becomes imperative to regularly detect and monitor the toxicity levels of OPPs in crops in order to aid policy makers in establishing appropriate limits for pesticide dosage, thus promoting safe agricultural practices. Several customary chromatographic methods, including gas chromatography ( GC ), gas chromatography-mass spectrometry ( GC-MS ), liquid chromatography, liquid chromatography-mass spectrometry ( LC-MS ) [ [22] , [23] , [24] , [25] , [26] , [27] ], and high performance liquid chromatography ( HPLC ) coupled with UV detector [ [28] , [29] , [30] ], are commonly employed for OPP detection. While these chromatographic techniques are considered more flourished and advanced, they come with certain limitations such as expensive instrumentation and complex sample preparation.…”

Competitive Assay for the Ultrasensitive Detection of Organophosphate Pesticides Based on a Fiber-Optic Particle Plasmon Resonance Biosensor and an Acetylcholinesterase Binding Peptide

“…Therefore, despite the associated high costs and low throughput, these techniques are often required as a confirmatory method. However, for the purpose of rapid on-site screening, biosensors have been suggested as a promising approach, as many of them have the potential to provide real-time quantitative information with minimum preparation using mobile setup. ,− …”

“…Antibody and aptamer are the two recognition elements mostly used for OP biosensors. , In this report, we propose a novel biorecognition element using the enzyme AChE from Musca domestica L., which has 692 residues and has pockets that serve different functions . The different residues present on the enzyme are responsible for the different activities of these pockets, as can be seen in Figure S1 .…”
