“…In that work, silver nanospheres and silver nanoprisms were used to detect four different pesticides: atrazine (herbicide), simazin (herbicide), irgarol (antimicrobial pesticide) and diuron (herbicide). Three of the pesticides, atrazine, simazin and irgarol, were all able to be detected down to millimolar concentrations 186 . A flexible cellulose nanofiber paper‐based substrate was developed by Li et al.…”

As the human population grows, the anthropogenic impacts from various agricultural and industrial processes produce unwanted contaminants in the environment. The accurate, sensitive and rapid detection of such contaminants is vital for human health and safety. Surface-enhanced Raman spectroscopy (SERS) is a valuable analytical tool with wide applications in environmental contaminant monitoring. The aim of this review is to summarize recent advancements within SERS research as it applies to environmental detection, with a focus on research published or accessible from January 2021 through December 2021 including early-access publications. Our goal is to provide a wide breadth of information that can be used to provide background knowledge of the field, as well as inform and encourage further development of SERS techniques in protecting environmental quality and safety. Specifically, we highlight the characteristics of effective SERS nanosubstrates, and explore methods for the SERS detection of inorganic, organic, and biological contaminants including heavy metals, pharmaceuticals, plastic particles, synthetic dyes, pesticides, viruses, bacteria and mycotoxins. We also discuss the current limitations of SERS technologies in environmental detection and propose several avenues for future investigation. We encourage researchers to fill in the identified gaps so that SERS can be implemented in a real-world environment more effectively and efficiently, ultimately providing reliable and timely data to help and make science-based strategies and policies to protect environmental safety and public health.

“…Surface-enhanced Raman spectroscopy (SERS) technology refers to the process after molecules are adsorbed on the surface of some rough metals (such as gold, silver, and copper), where the electromagnetic field on the metal surface or near surface is enhanced in the excitation area, which enhances the Raman signal intensity of adsorbed molecules [ 18 ]. SERS has the advantages of high detection sensitivity, simple sample pretreatment, fast analysis speed, low detection cost, and in situ detection, which has been used for the rapid detection of food additives and pesticide residues in food and agricultural products [ 19 , 20 ]. The SERS enhanced effect was closely related to the substrate material.…”

Chlorpyrifos is an organophosphorus insecticide, which can be used to control a variety of chewing and piercing mouthparts pests in agricultural production. It can destroy the normal nerve impulse conduction by inhibiting the activity of acetylcholinesterase or cholinesterase in the nerves, causing a series of poisoning symptoms. In order to achieve the quantitative analysis of chlorpyrifos residues in agricultural products, an aptamer-controlled signal molecule release method was developed in this study. The signal molecule 4-ATP of surface-enhanced Raman spectroscopy (SERS) was loaded into aminated mesoporous silica nanoparticles (MSNs-NH2) prepared by the one pot method, and then coated with an aptamer of chlorpyrifos through electrostatic interaction. The specific binding of the aptamer and chlorpyrifos led to the release of 4-ATP, and the amount of 4-ATP released was positively correlated with the amount of chlorpyrifos. Finally, the standard curve of chlorpyrifos quantitative detection based on SERS was established. Meanwhile, Ag-carrying mesoporous silica (Ag@MSNs) was prepared as the reinforcement substrate for SERS detection. The results showed that there was a good linear correlation between the Raman intensity and the concentration of chlorpyrifos at 25–250 ng/mL, and the limit of detection (LOD) was 19.87 ng/mL. The recoveries of chlorpyrifos in the apple and tomato samples were 90.08–102.2%, with RSD < 3.32%. This method has high sensitivity, specificity, reproducibility and stability, and can be used for the quantitative detection of chlorpyrifos in the environment and agricultural products.

“…So it is very important to develop a rapid, sensitive and accurate method to detect multiple pesticides simultaneously. Now, the detection methods of pesticide residues include Raman spectroscopy, 7 near infrared spectroscopy, 8 enzyme linked immunoassay, 9 capillary electrophoresis, 10 thin layer chromatography, 11 gas chromatography-mass spectrometry (GC-MS), 12 liquid chromatography-mass spectrometry (LC-MS) 13 and so on. But, there are also many problems with these analytical methods.…”

We have developed a new method of one-step simultaneous detection for three pesticides including acetamiprid, atrazine and carbendazim based on organic framework nanomaterial Cu/UiO-66 and three different fluorescent dyes-labeled pesticide aptamers.Cu/UiO-66 can be easily combined with pesticide aptamers through strong coordination, then aptamers were adsorbed to the surface of Cu/UiO-66, which brings the dyes and Cu/UiO-66 into close proximity. And then, the fluorescence of dyes were quenched by Cu/UiO-66. When the target pesticides appeared, the aptamers reacted with corresponding target pesticides and formed special spatial structure, then the dyes were far away from the surface of Cu/UiO-66 and the fluorescence of dyes is resumed. Thus, the one-step simultaneous detection for three pesticides can be achieved by synchronous fluorescence analysis. The detection limit of acetamiprid, atrazine and carbendazim were 0.1 nmol/L, 1.6 nmol/L and 0.3 nmol/L, respectively. This method has a good sensitivity, low detection limit and high selectivity.
