Quantum dots (QDs) and fluorophores with different emission wavelengths can also be used in multi-label strategies. For multi-residue detection, MIPs have been applied as recognition elements with good anti-matrix effects. Therefore, multi-residue detection methods are more favorable for the actual analytical needs of end-users. Jamshidi B., Mohajerani E., Jamshidi J. The ideal ratio of mixed antibodies should be carefully optimized. Veterinary drugs are commonly administered in farming practices for the prevention and treatment of diseases and promoting growth [3]. Sensitive detection was also realized in the SERE detection. Quantitative detection can also be achieved, as the degree of inhibition is related to the concentration of pesticide residues [94]. Copyright Elsevier, 2015. Discusses application of this research to inform risk assessment and policy related to pesticide drift. Reproduced with permission from [115]. In this category, enzymatic inhibition-based sensors, near-infrared (NIR) spectroscopy, and SERS spectroscopy are introduced.

The best successive projections algorithm multiple linear regression model was used to transfer the distribution of the pesticide residues to a visualization map. However, MIPs fabricated by traditional methods have high selectivity to the target analyte, which limits their application in multi-analyte analysis. Two luciferasesfirefly luciferase and Renilla luciferasewere used to label broadly specific single-chain variable fragments against FQs and SAs (Figure 4A). AuNPs labeled antibodies were mixed in microwells (Figure 3A). However, the spectra used in the above methods were collected from a small portion of the tested samples, which cannot guarantee the data accuracy and representativeness. The coating antigens of three OPs in microtiter plate wells competed with the OPs in the sample to bind the antibodies on AuNP probes. Song E., Yu M., Wang Y., Hu W., Cheng D., Swihart M.T., Song Y.

NIR fluorescence was used to label broad-specificity monoclonal antibodies. Reproduced with permission from [84]. Please click here to see any active alerts. Taking organophosphorus pesticides (OPs) for example, the commonly used OPs usually contain an aromatic ring and a thiophosphate moiety. For example, the above OP broad-spectrum aptamer SS2-55 has been used in colorimetric, electrochemical, and SERS assays [65]. With the development of genetic manipulation and hybridoma technology, bispecific antibodies composed of two different heavy/light chains have been widely used as broadly specific antibodies (Figure 2C). Aside from quality assessment and food compounds measurement, NIR spectroscopy has been shown to have feasibility for the detection of pesticide and veterinary drug residues, in order to ensure food safety [104]. The purpose of this experiment was to determine if methanol could be used as an alternative to dichloromethane as the extract solvent used in the raspberry pesticide detection assay. Barriada-Pereira et al. [115] constructed an Au-decorated dragonfly wing bioscaffold array as a flexible SERS substrate for the detection of three kinds of pesticides. For practical applications, flexible SERS substrates consisting of SERS active nanomaterials and flexible solid substrates are useful for the detection of surface residues.

EPA PFAS Tests Pesticides: EPA Goal Stop PFAS Entering Environment Hyperspectral imaging integrated spectroscopy and imaging can be used to obtain both spectral and spatial information from samples [107]. The traditional methods for pesticide and veterinary drug residues determination are usually based on instrumental techniques such as gas chromatography (GC), high performance liquid chromatography (HPLC), or chromatographic methods coupled with mass spectrometry (MS) detectors [ 8 ]. Therefore, various Au and Ag SERS substrates have been applied for the simultaneous detection of pesticide and veterinary drug residues. SERS is a promising method, combining Raman spectroscopy and nanotechnology for the rapid and non-invasive detection of samples. Li H., Ma S., Zhang X., Li C., Dong B., Mujtaba M.G., Wei Y., Liang X., Yu X., Wen K., et al.

This review also highlights modern methods of sample preparation, such as QuEChERS, SPME, PLE, dLLME, and ADLL-ME, as well as the most used methods of separation and identification of pesticides in grapes. Based on this principle, enzymatic inhibition-based multi-residue detection can be applied in multi-analyte monitoring [95]. Pesticides are widely applied in modern agriculture to control weeds and pests and regulate the growth of plants [2]. (2013) also demonstrated an improved method to detect phosmet, azinphos-methyl, and AChE can hydrolyze certain substrates to colored products, while the color development can be decreased in the presence of OP or CM pesticides [96].
