“…Within fungicide detection, we evaluated promising methods for THR detection, such as the use of Ag/WO3‐x substrates 140 and MXene/AuNR substrates, 139 both of which allow for highly sensitive detection. For herbicide detection, we highlighted a novel method for atrazine quantification using a silver nanoprism/GO/SiNW array, 183 as well as an AgNP array‐based substrate which avoided the coffee ring effect by using hydrophobic lotus leaves 188 . In applying SERS to insecticide detection, multiple methods have been able to achieve trace detection, such as the Au‐PdNPs, Ag‐PdNPs, 194 and PSi‐PD NPs 202 substrates discussed previously.…”

“…183 Another recent study by Yao et al used natural lotus leaves as hydrophobic surfaces to detect PQ. 188 AgNPs synthesized through a citrate-reduction method were mixed with PQ solutions and then applied to the lotus leaves. During evaporation, the AgNPs arranged themselves into arrays on a small area of the lotus leaves, instead of leaving a coffee ring of AgNP aggregates.…”

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.

“…In this work, the entire analysis was completed within 1 min without treatment. Yao et al [ 81 ] developed a simple SERS sensor modified by Ag nanoparticles (NPs) that can generate many hot spots for SERS enhancement. When the sensor was applied to determine PQ, there was a good linearity between the SERS signal intensity of PQ and its concentration, and the detection range was wide, from 5 ng/mL to 50,000 ng/mL.…”

Paraquat (PQ) and diquat (DQ) are quaternary ammonium herbicides which have been used worldwide for controlling the growth of weeds on land and in water. However, PQ and DQ are well known to be toxic. PQ is especially toxic to humans. Moreover, there is no specific antidote for PQ poisoning. The main treatment for PQ poisoning is hemoperfusion to reduce the PQ concentration in blood. Therefore, it is essential to be able to detect PQ and DQ concentrations in biological samples. This critical review summarizes the articles published from 2010 to 2022 and can help researchers to understand the development of the sample treatment and analytical methods for the determination of PQ and DQ in various types of biological samples. The sample preparation includes liquid–liquid extraction, solid-phase extraction based on different novel materials, microextration methods, and other methods. Analytical methods for quantifying PQ and DQ, such as different chromatography and spectroscopy methods, electrochemical methods, and immunological methods, are illustrated and compared. We focus on the latest advances in PQ and DQ treatment and the application of new technologies for these analyses. In our opinion, tandem mass spectrometry is a good choice for the determination of PQ and DQ, due to its high sensitivity, high selectivity, and high accuracy. As far as we are concerned, the best LOD of 4 pg/mL for PQ in serum can be obtained.

“…Considering these issues, researchers are currently looking for alternative approaches by which reproducible SERS substrates can be obtained either from naturally or commercially available patterned nanostructures. Among these, lotus leaf [26] and diatom frustules [27], printing grade papers [28], polymer nanofibers [29], bio-polymer [30], compact discs (CDs) [31,32] blu-ray digital versatile disc (BR-DVD) [33,34] substrates have been widely used for the fabrication of SERS substrates.…”

Detection and estimation of various biomolecular samples are often required in research and clinical laboratory applications. Present work demonstrates the functioning of a surface‐enhanced Raman scattering (SERS) substrate that has been obtained by drop‐casting of citrate‐reduced gold nanoparticles (AuNPs) of average dimension of 23 nm on a bare blu‐ray digital versatile disc (BR‐DVD) substrate. The performance of the proposed SERS substrate has been initially evaluated with standard Raman active samples, namely malachite green (MG) and 1,2‐bis(4‐pyridyl)ethylene (BPE). The designed SERS substrate yields an average enhancement factor of 3.2 × 106 while maintaining reproducibility characteristics as good as 94% over the sensing region of the substrate. The usability of the designed SERS substrate has been demonstrated through the detection and analysis of purified rotavirus double‐stranded RNA (dsRNA) samples in the laboratory environment condition. Rotavirus RNA concentrations as low as 10 ng/μL could be detected with the proposed sensing scheme.
