“…However, among numerous examples that we have mentioned above, there is only one sensor that can detect more than one molecule at once. It is the sensing systems for 3 kinds of pesticides by Zhang et al in 2020, 158 in which 3 different fluorescence signals from 3 kinds of fluorophores were recorded, analyzed in RGB model to calculate the contents of each kind of pesticides. However, a fluorescence-based sensor always requires some instruments and tools to record and analyze the signals.…”

“…Various biological molecules, such as antibodies [116,117], nucleic acids [118][119][120], amino acids [121,122] can be used for direct conjugation with AuNPs. Fluorescence-based immune assay techniques have been used to detect different type of pesticides [123][124][125]. Zhang et al [123] used fluorescently labelled oligonucleotide and AuNP signal amplification technology to develop a multi-analyte fluorescence immunoassay for detection of three organophosphate pesticides (triazophos, parathion and chlorpyrifos) in various agro-products (rice, wheat, cucumber, cabbage and apple).…”

Heavy metal ions and pesticides are extremely dangerous for human health and environment and an accurate detection is an essential step to monitor their levels in water. The standard and most used methods for detecting these pollutants are sophisticated and expensive analytical techniques. However, recent technological advancements have allowed the development of alternative techniques based on optical properties of noble metal nanomaterials, which provide many advantages such as ultrasensitive detection, fast turnover, simple protocols, in situ sampling, on-site capability and reduced cost. This paper provides a review of the most common photo-physical effects impact on the fluorescence of metal nanomaterials and how these processes can be exploited for the detection of pollutant species. The final aim is to provide readers with an updated guide on fluorescent metallic nano-systems used as optical sensors of heavy metal ions and pesticides in water.

“…The sensitivity of analysis was improved and the LOD for each antibiotic was 5 pg/mL. Zhang et al [61] employed fluorescently labeled oligonucleotide and an AuNP signal amplification strategy to develop a multi-analyte FLISA for the detection of three OPs (triazophos, parathion, and chlorpyrifos). Three antibodies and their corresponding fluorophore-labeled oligonucleotides were conjugated on AuNP probes.…”

Rapid Multi-Residue Detection Methods for Pesticides and Veterinary Drugs

View full text Add to dashboard Cite

The excessive use or abuse of pesticides and veterinary drugs leads to residues in food, which can threaten human health. Therefore, there is an extremely urgent need for multi-analyte analysis techniques for the detection of pesticide and veterinary drug residues, which can be applied as screening techniques for food safety monitoring and detection. Recent developments related to rapid multi-residue detection methods for pesticide and veterinary drug residues are reviewed herein. Methods based on different recognition elements or the inherent characteristics of pesticides and veterinary drugs are described in detail. The preparation and application of three broadly specific recognition elements—antibodies, aptamers, and molecular imprinted polymers—are summarized. Furthermore, enzymatic inhibition-based sensors, near-infrared spectroscopy, and SERS spectroscopy based on the inherent characteristics are also discussed. The aim of this review is to provide a useful reference for the further development of rapid multi-analyte analysis of pesticide and veterinary drug residues.
