“…Classical instrumental analytical techniques for the determination of pesticides in a large number of samples have been developed. These methods involve GC and LC coupled with various detectors 90 , 91 , 92 , GC-MS 93 , 94 , or LC-MS 91 , 95 . In recent years, GC-MS/MS has been intensively used for the determination of pesticides 96 , 97 .…”

The safety of traditional Chinese medicine (TCM) is a major strategic issue that involves human health. With the continuous improvement in disease prevention and treatment, the export of TCM and its related products has increased dramatically in China. However, the frequent safety issues of Chinese medicine have become the ‘bottleneck’ impeding the modernization of TCM. It was proved that mycotoxins seriously affect TCM safety; the pesticide residues of TCM are a key problem in TCM international trade; adulterants have also been detected, which is related to market circulation. These three factors have greatly affected TCM safety. In this study, fast, highly effective, economically-feasible and accurate detection methods concerning TCM safety issues were reviewed, especially on the authenticity, mycotoxins and pesticide residues of medicinal materials.

“…The comparisons of the SERS column for quantitative detection of phosmet in current work with the results in literature using other SERS substrates are listed in Table 1. It is summarized the present reported other techniques for phosmet detection, including surface plasmon resonance sensor [33], gas chromatography with flame photometric detection [34], gas chromatography-tandem mass spectrometry [1], enhanced chemiluminescence enzyme linked immunosorbent assay [35] and SERS substrates, including Klarite substrates [31], Q-SERS substrates ™ [36], graphene-gold film-gold nanorod [37], solid-phase extraction-SERS [20], gold nanoparticles functionalized glycidyl methacrylate-ethylene dimethacrylate [21] substrates. It is clearly observed that the SERS column we reported has a best position among the SERS substrates, and is as good as other techniques.…”

We have developed a simple, sensitive and practical substrate for surface enhanced Raman scattering (SERS). It consists of a column material that is obtained by modifying the surface of (glycidyl methacrylate)-co-(ethylene dimethacrylate) capillary monoliths with silver nanoparticles. This new SERS column substrate was applied to the determination of 4-mercaptopyridine (4-Mpy) and Rhodamine 6G (R6G) to give detection limits as low as 100 and 10 pM, respectively. The calculated enhancement factor is approximately 1.2×10 8 . This represents a substantial improvement over conventional colloidal substrates. The new substrate was applied to the determination of residues of the pesticide phosmet and gave a detection limit of 3 μg L −1 , with a linear response in the 3 to 1000 μg L −1 concentration range (R 2 = 0.995). Additionally, 0.2 mg kg −1 of phosmet on apples and oranges, and of 0.5 mg kg −1 on tea leaves were detectable via SERS using this column along with a simple extraction process. The above LODs are well below the tolerance level prescribed by National Standard of China. Thus, this simple method is highly efficient, sensitive, and affordable and introduces a SERS-based trace detection suitable for real-world applications, especially for the determination of pesticides.

“…Therefore, the threats ultimately pose the need for the detection of OPs and CBs. More highly sensitive methods have been developing for the determination of OPs and CBs, such as gas-chromatography (GC), [4][5][6][7][8][9] high performance liquid chromatography (HPLC), GCmass spectrometry (MC), [10][11][12][13] and HPLC-MC. 14 15 These methods can effectively detect the concentrations of different compounds and, at the same time, require complicated sample pretreatments, highly trained technicians and very expensive equipments.…”

Recent research progress is reviewed in development of rapid detection of Organosphorous (OPs) and carbamates (CBs) pesticide based on acetylcholinesterase (AChE) inhibition principle. Enzyme biosensors have properties that can provide conveninent, rapid, sensitive and cheap on-field detection with AChE. In recent years, effective monitoring of OPs and CBs pesticides has been done successfully by using nanomaterials-based AChE sensors. More and more nanomaterials such as modified carbon nanotubes, nanocomposite material, modified gold nanoparticles, quantum dots(QDs) are applied to enzyme biosensors, the modified electrodes can promote significant enhancements of determinations of pesticide residues.
