“…This method was successfully used to detect and quantify Hg 2+ in lake water samples several orders of magnitude below the USEPA limits for permissible concentrations in drinking water 99 . A different study proposed a novel SERS aptasensor with dual‐recycling amplification for Hg 2+ detection, combining SERS with nucleic acid signal amplification to obtain a more sensitive detection 86 . Dual‐recycling amplification involves the immobilization of aptamers onto a substrate and bound with a complementary DNA strand, which will cleave off once the target molecule is introduced and is captured by the aptamer.…”

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.

“…1 As a developing analytic technique, SERS shows many unique advantages including a low detection limit, wide detection range, high-throughput, and quick response, thus attracting increasing interest in many fields including surface science, 2 materials science, 3 biomedicine, 4 drug analysis, 5 food safety, 6 environmental testing and so on. 7,8 However, the current general view holds that SERS tends to have a large bias in quantitative analysis, 9,10 which severely limits the application of SERS technology. Therefore, it is particularly important to improve the reliability of SERS in quantitative analysis.…”

MXene is a two-dimensional (2D) nanomaterial that exhibits several superior properties suitable for fabricating biosensors. Likewise, the nucleic acid (NA) in oligomerization forms possesses highly specific biorecognition ability and other features amenable to biosensing. Hence the combined use of MXene and NA is becoming increasingly common in biosensor design and development. In this review, MXene- and NA-based biosensors are discussed in terms of their sensing mechanisms and fabrication details. MXenes are introduced from their definition and synthesis process to their characterization followed by their use in NA-mediated biosensor fabrication. The emphasis is placed on the detection of various targets relevant to agricultural and food systems, including microbial pathogens, chemical toxicants, heavy metals, organic pollutants, etc. Finally, current challenges and future perspectives are presented with an eye toward the development of advanced biosensors with improved detection performance.
