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.</p>","PeriodicalId":93411,"journal":{"name":"Analytical science advances","volume":"3 3-4","pages":"113-145"},"PeriodicalIF":0.0,"publicationDate":"2022-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/ansa.202200003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92308204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Workflows can be simplified through the elimination of sample preparation, analysis times can be significantly reduced and analysis remote from the traditional laboratory space has become a real possibility. As such, the interest in AIMS has rapidly spread through analytical communities worldwide, and AIMS techniques are increasingly being integrated with standard laboratory operations. This annual review covers applications of AIMS techniques throughout 2021, with a specific focus on AIMS applications in a number of key fields of research including disease diagnostics, forensics and security, food safety testing and environmental sciences.

They are found in diverse environments ranging from paddy fields to animal digestive tracts to deep-sea hydrothermal vents. Investigating their distribution and physiological activity is crucial for the detailed analysis of the dynamics of greenhouse gas generation and the search for the environmental limits of life. In methanogens, cobamide cofactors (vitamin B₁₂ analogs) play a key role in methane synthesis and carbon fixation, thus serving as a marker compound that metabolically characterizes them. Here, we report on resonance Raman detection of cobamides in methanogenic cells without destroying cells and provide structural insights into those cobamides. We succeeded in detecting cobamides in four representative methanogens <i>Methanosarcina mazei</i>, <i>Methanosarcina barkeri</i>, <i>Methanopyrus kandleri</i>, and <i>Methanocaldococcus jannaschii</i>. The former two are mesophilic, cytochrome-containing methanogens, whereas the latter two are hyperthermophilic, non-cytochrome-containing methanogens. The 532 nm-excited Raman spectra of single or multiple cells of the four species all showed resonance Raman bands of cobamides arising mainly from the corrin ring, with the most intense one at ∼1500 cm⁻¹.
