Traditionally used HPLC and mass spectrometry-based assays suffer from several drawbacks, including lengthy sample preparation, heavy instrumentation, and the need for expert technicians. Specific, measurable, accurate, robust, and time-saving (SMART) biosensors are needed to detect toxic substances. Aptamers provide unique opportunities for the rapid development of SMART biosensors to meet above challenges. Since aptamers are short nucleotide sequences; they are easy for chemical synthesis and functional modifications. Aptamers acquire specific molecule recognition potential through unique chemical bonding, including H-bonds, pi-pi, van der Waals, and hydrophobic interactions. For the discovery of aptamers, the SELEX process is used. Recently, efforts have been made to develop aptamers to detect toxic small molecules like antibiotics, pesticides, insecticides, pollutants, toxins, and allergens. Aptamer technology is a promising tool for analyzing these chemicals from diverse matrices. This review provides an update on advances in nucleic acid-based aptameric sensors for molecular diagnostics of toxic chemical from food, water, human fluids, and the environment.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2214158822000319/pdfft?md5=b25504f726cb93dfcfb6f6f62da7bc7e&pid=1-s2.0-S2214158822000319-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47175011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review provides the summary of studies on pesticides analysis in soil based on chromatography-coupled methods published between 2015 and 2022. We discuss the shift toward faster, greener, and simpler alternatives to conventional techniques, application of sample preparation and detection methods to targeted and untargeted pesticide analysis, as well as the developments in stereoselective determination of chiral pesticides. The sample preparation methods such as solid-phase extraction, dispersive solid-phase extraction, and derived methods, as well as the recent trends and developments in chromatographic separation of pesticides are covered in this review. For sample preparation, the QuEChERS method is replacing other techniques and has proved to be efficient in both screening and accurate quantification in multiresidue analysis. Shift towards minimal sample preparation is supported by a wider application of highly sensitive and selective separation and detection systems such as LC-MS/MS. The features of different methods of sample preparation and detection are discussed with focus on optimal parameters, advantages, and drawbacks. The optimal parameters of sample preparation methods were summarized based on respective publications, which makes the review a useful tool for method development and further investigations.</p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46560904","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}

This review examines the role of MPs as vectors of environmental emerging contaminants. First, the main tools used to identify and characterise MPs and the analytical methods used for the determination of associated emerging contaminants are discussed. Insightful explanations of the sorption interaction between several groups of emerging pollutants and MPs are provided. MP type (polarity, crystallinity, size) and aging process together with the environmental conditions and pollutant properties (hydrophobicity and dissociated forms) are key factors influencing the sorption process. The literature review showed that polyethylene and polystyrene were the most commonly studied polymers. Antibiotics, perfluoroalkyl compounds and triclosan showed high sorption capacities onto MPs. Finally, the effect of co-exposure to MPs-emerging pollutants and bioaccumulation in aquatic and terrestrial organisms is discussed. The combined exposure may impact the toxic effects in different ways, through synergistic or antagonic interactions. Examples of different scenarios are provided, but in general the research conducted on terrestrial systems is scarce.
