However, their presence in natural water systems is a significant concern due to their persistent composition and complex molecular structures. Additionally, their toxic and recalcitrant nature poses potential risks, leading to chronic health effects in humans. Typically detected in trace concentrations, pesticides present analytical challenges owing to their intricate chemical structures and diverse physical properties. Recent research highlights notable advancements in conventional pesticide extraction methods, aiming to develop eco-friendly and cost-effective techniques with high enrichment and recovery rates. This review begins by exploring the latest trends and ongoing research related to the occurrence and extraction of pesticides from various aquatic environments. The study then discusses the innovative extraction techniques currently employed for pesticide removal. Among liquid-phase microextraction (LPME) techniques, methods such as ionic liquid-based extraction (IL-LPME), deep eutectic solvent-based extraction (DES-LPME), air-assisted extraction, solidification of a floating organic drop (SFO), and ultrasound-assisted LPME are gaining attention due to their ease of handling, operational simplicity, cost-effectiveness, and environmental sustainability. In the, solid-phase extraction (SPE) field, researchers have increasingly utilized approaches like magnetic solid-phase extraction (MSPE), green sorbents, metal-organic framework (MOF) based extraction, cartridge-based SPE, and carbon nanotube-based SPE as the most widely adopted methods. These methods are preferred for their benefits, including efficient separation, rapid analysis, and environmentally sustainable practices. The latter sections of this review present a detailed comparative analysis of these extraction methods, evaluating critical parameters such as operational time, cost, chemical and energy consumption, and analytical accuracy.</p>","PeriodicalId":435,"journal":{"name":"Talanta","volume":"293 ","pages":"128094"},"PeriodicalIF":5.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143958432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quetiapine (QTP), as one of the newly developed antipsychotic drugs, may pose risks to human health if used improperly.

The prepared negatively charged MXene was first assembled on the surface of the NFs through electrostatic interaction to form MXene/NFs, and then the prepared AuNRs were anchored on the MXene/NFs to obtain the final 3D AuNRs/MXene/NFs. By integrating the porous structure and magnetic properties of NFs, large specific surface area of MXene, and the plasmonic hot spots of Au nanorods, the AuNRs/MXene/NFs-based SERS platform can easily and sensitively detect QTP in human urine with the limit of detection of 1.71 × 10^-9 mol/L.

We presented a curcumin in situ grafted MOF magnetic material (Fe₃O₄/MOF-Cur) for dual-functionalized applications of fluoride detection and adsorption. Owing to the electrostatic interaction, ligand exchange at the metal sites and boron-fluorine complexation, the adsorption capacity of Fe₃O₄/MOF-Cur for fluoride is 99.92 mg/g, and the detection limit is 1.17 μM. The fluoride adsorption behavior on different active units was further visualized by theoretical calculations. Favorable stability (79.52 mg/g after 5 adsorption-desorption cycles and insignificant change of fluorescence intensity within 30 days), mild reaction conditions (pH = 3-5) and excellent anti-interference ability promote the application of Fe₃O₄/MOF-Cur in real samples. Finally, the paramagnetic properties (29 emu/g) allow for easy recovery from water.

Here, we report an ultrasensitive, rapid, and low-cost method for detection of the most popular sepsis biomarker, procalcitonin (PCT), based on a split aptamer-based fiber optic nanogold-linked sorbent assay. After successful development of a novel aptamer for PCT by SELEX, a pair of split aptamer fragments from the parent aptamer was predicted through molecular interaction simulation via free webservers. Then one fragment (AptF1) is modified on a sensor fiber and the other fragment (AptF2) is conjugated to a gold nanoparticle (AuNP@AptF2). The interactions among PCT and the two aptamer fragments lead to the formation of a AuNP@AptF2-PCT-AptF1 sandwich-like nanocomplex on the fiber core surface, leading to strong nanoplasmonic absorption near the fiber core surface. This method provides a linear response ranging from 500 fg/mL to 5.0 ng/mL and a detection limit of 50 fg/mL (3.9 fM).

In this study, we developed a novel ratiometric fluorescent immunosensor for fenitrothion (FN) detection by employing chitosan-modified platinum nanoparticles (Ch-Pt NPs) as catalytic nanozymes. Ch-Pt NPs exhibit oxidase-mimicking activity, enabling the oxidation of ascorbic acid (AA) and o-phenylenediamine (OPD) to produce dehydroascorbic acid (DHAA) and 2,3-diaminophenazine (DAP, Em = 568 nm), respectively. Then, DHAA further reacted with the remaining OPD to generate quinoxaline derivatives (DFQ, Em = 430 nm). These two products further form ratiometric fluorescent signals. Taking AA as a breakthrough point, the dual-catalytic cascade of natural enzymes and nanozymes was achieved by the combination with the alkaline phosphatase (ALP) -based enzyme-linked immunosorbent assay (ALP-ELISA). Compared with the conventional colorimetric ELISA, the proposed sensor demonstrated a nearly 20-fold enhancement in sensitivity (detection limit: 0.48 ng/mL) and achieved satisfactory recoveries of 80.0-108.3 % in spiked samples.
