Achieving rapid, sensitive detection of contaminants is extremely important for timely environmental pollution monitoring and treatment. Quantum dot (QD) probes have become a common method for the detection of contaminants. In particular, the development of QDs based on nonmetallic element-doped carbon materials QDs and other nonmetallic doped Si QDs, MoOx QDs, MoS₂ QDs, and MXene QDs provides a more convenient and effective means of detecting pollutants. However, a comprehensive summary of the application of nonmetal-doped QD probes for contaminant detection is still lacking. To address this issue, in the present work we mainly categorize different nonmetal-doped QDs into “top-down” and “bottom-up” strategies based on their preparation methods. QD probes based on nonmetal doping have unique optical properties, such as a narrow excitation spectrum, optical tunability, high fluorescence quantum yield (QY), and fluorescence stability. Fluorescence sensing technology can be realized through sensing mechanisms such as fluorescence/dynamic quenching, photoinduced electron transfer (PET), internal filtering effect (IFE), and fluorescence resonance energy transfer (FRET). Considering the ease of implementation, operation, and immediate response of fluorescence sensing technology, it has been widely used in research for the detection of environmental pollutants. We have found that fluorescence sensing technology based on nonmetal-doped QD probes can achieve rapid detection of pollutants (such as heavy metals in water or food, harmful nonmetallic ions, organic pesticides, and antibiotic residues), and its limit of detection (LOD) can reach the picomolar level for trace detection. In addition, the fluorescence sensing technology of nonmetallic QD probes can be combined with smart devices to realize real-time monitoring of pollutants. Our work provides additional strategies for developing nonmetal-doped QD probe-based detection of contaminants and advancing future environmental governance.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92046622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concerns on PFAS arise from the very high stability, bioaccumulation potential and toxicity and the ubiquitous occurrence in humans, animals, soils, sediments, surface, ground and </span>drinking waters. Advanced analytical methods are needed to investigate the input and fate of PFAS and potential transformation products in the environment and the exposure pathways for humans and wildlife. Therefore, nontarget screening (NTS) methods by high-resolution mass spectrometry (HRMS) coupled to chromatography are often applied to meet the analytical challenges arising from the high number and chemical diversity of individual compounds, the lack of authentic standards and information on identity and application areas. In this critical review we discuss the recent advances of NTS workflows applied to detect and identify PFAS based on the intrinsic information contained in data from chromatography and HRMS data on the MS</span>¹ and MS² level. This includes retention time and peak shape characteristics, data on accurate mass and isotopologues, and high-resolution mass fragments. Successful approaches for prioritization and identification of PFAS are mostly based on mass defect filtering, Kendrick mass defect analysis, mass matches with suspect lists, assignment of chemical formulas, mass fragmentation patterns, diagnostic fragments and fragment mass differences. So far NTS approaches for PFAS were able to identify more than 750 compounds. However, still limited applicability of chromatography and ionization methods and limited mass resolving power and accuracy largely restrict a complete identification of a high number of unknown PFAS in complex samples from environmental compartments and biota.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2023-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49715091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
