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.

“…Production of noble-metal nanoparticles with anisotropic morphologies, such as nanocubes, nanorods, nanostars, and nanoprisms, has intrigued researchers’ attention due to their unique electrical, optical, and chemical properties along with superior surface plasmon resonance action. − Among those, silver nanoprisms (Ag NPrs) obtain extensive interest due to their high electric field enhancement around the mighty sharp tips and edges, which provide vigorous surface plasmon resonances through the lightning rod effect. Parallel to this, the enhanced electric field intensity can be generated between two adjacent sharp tips named “hotspots”, which not only can increase the LSPR action but also can be utilized in the sensitive detection by tip-based sensors. − However, the noble-metal-based SERS substrates possess some inevitable disadvantages, such as poor stability, easy oxidation, high cost, and poor signal reproducibility . To overcome this issue, various noble-metal incorporated heterostructures are developed by utilizing a semiconductor, layered double hydroxides, and metal–organic framework due to their superior biocompatibility, rich variety, low cost, and outstanding chemical stability. − Among those, the combination of noble-metal and semiconductor materials as an SERS substrate has been extensively investigated due to their combined characteristics to help to enhance the plasmonic behavior of noble metals and their stability.…”

The construction of noble-metal incorporated semiconductor hybrids for the detection of antibiotics has intrigued great interest among researchers in the field of surface-enhanced Raman spectroscopy (SERS). However, the production of SERS substrates to accomplish the effective enhancement of the Raman signal was a bottleneck to researchers for the past decades. This study investigates the SERS performance of anisotropic Ag nanoprisms (Ag NPrs) attached onto the surface of Cu2O microspheres for the trace-level antibiotic detection of nitrofurazone (NFZ). Physicochemical activities and surface morphologies of the prepared hybrids were meticulously examined using various analytical techniques. The eminent sharp tips and edges of Ag NPrs deposited on Cu2O microspheres endow enormous intensity enhancement of the Raman signal of NFZ in the innumerable hotspot regions through the synergistic utilization of electromagnetic enhancement and charge transfer enhancement. The proposed hybrid-based SERS substrate provides superior detection performance, including high sensitivity, high enhancement factor of 2.31 × 1011, ultra-low limit of detection of 5.80 × 10–13 M, superior spot-to-spot uniformity, and substrate-to-substrate reproducibility <8.31% for NFZ detection. Furthermore, the real-sample analysis performed on NFZ in local pond water shows satisfactory recovery values from 81 to 96%. The presented sensing characteristics demonstrate that the proposed Ag-NPrs/Cu2O-based SERS substrate possesses promising features for detecting NFZ in standard and real-sample applications.

The increasing demand for single‐use plastic‐based products worldwide has generated immense waste during the last decade. This review aims to summarize the current developments of surface‐enhanced Raman spectroscopy (SERS) for detecting micro‐ and nanoplastics in a variety of samples and environments. Despite the SERS technique being very recent for this purpose, its robustness has already been discussed in a few analyses focused on well‐known pollutants such as phthalates, plasticizers, and xenobiotic contaminants from commercially available water bottles. Here, the latest advances, obstacles, and perspectives are reviewed using SERS detection as a robust alternative for analyzing complex samples containing nanoplastic particles present in daily consumer products such as wine and vegetables. Moreover, this paper describes different SERS substrates developed to overcome the limitations for identifying polymer particles at low concentrations. Factors contributing to the sensitivity of SERS substrates are discussed to show the advantages and limitations of this technique. The broader role of SERS as a tool in environmental research is currently explored from polluted air and aquatic environments, which can be relevant for other fields, such as clinical monitoring and nanotoxicology.
