{"title":"A nano-crystalline Hf(IV) MOF for precise fluorometric recognition of carcinogenic nicotine and herbicide benfluralin: characterization, real-Life application and mechanistic investigation","authors":"Srijan Mukherjee, Sandip Roy, Pitam Chakrabarti, Vishal Trivedi, Shyam Biswas","doi":"10.1039/d5en00141b","DOIUrl":"https://doi.org/10.1039/d5en00141b","url":null,"abstract":"Metal-organic frameworks (MOFs) are emergent smart materials with significant potential in rapid fluorescence-based recognition of toxic organic pollutants. Nicotine (NIC), an extensively consumed neurotetratogenic alkaloid with addictive properties, and benfluralin, a broadly used herbicide, are both potent toxic organic pollutants with several serious health impacts. Extensive exposure of NIC and benfuralin in the environment poses an imperative demand for the development of a reliable sensor for dual recognition of NIC and benfluralin and mitigating the release of toxic substances. Therefore, we have constructed a robust nano-crystalline Hf-based MOF, 1ʹ for fluorescence-based aqueous phase turn-on detection of NIC, in addition to turn-off-based recognition of benfluralin in MeOH medium. Fluorogenic nano-crystalline sensor 1ʹ selectively detects both the targeted analytes with higher precision, even in nanomolar concentration. Moreover, the extended investigation was conducted using the probe 1ʹ for quantitative detection and monitoring of NIC in biofluids, real wastewater specimens and tobacco leaf extracts. Additionally, the capability of 1ʹ in recognition of NIC in live MDAMB-231 breast cancer cells was demonstrated through cell imaging. Furthermore, a biocompatible, cost-effective 1ʹ@chitosan@paper composite strip was demonstrated for instantaneous detection of NIC and benfluralin through a visible change in fluorescence response. Furthermore, a detailed mechanistic investigation was performed to validate a plausible mechanistic pathway for the observed optical response of 1ʹ in the presence of both NIC and benfluralin. This work offers a new approach to precisely monitor and reduce the release of toxic NIC and benfluralin, thereby contributing in safeguarding public health and the environment.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"48 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144640388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a toluene dispersion strategy for detecting microplastics of different sizes using surface-enhanced Raman spectroscopy (SERS). The evaporation-induced self-assembly (EISA) method was employed to prepare SERS substrates by incubating silver nanoparticles (AgNPs) of ~40-60 nm with a microplastic solution containing polystyrene (250 μm, 2.1 mm), polypropylene (10-50 μm), and polyvinyl chloride (1-5 μm). SEM images and Raman spectroscopy confirmed the uniform decoration of AgNPs on filter paper substrates, with a relative standard deviation (RSD) of 8.22%. Thiophenol was used as a Raman reporter to monitor surface changes, showing a strong correlation (R² = 0.986-0.995) between its SERS signal and microplastic concentration in aqueous and real samples. This is the first time a toluene dispersion strategy has been integrated with EISA to achieve highly sensitive microplastic detection, reaching a limit of 0.001 mg/mL. The method was validated in real-world matrices, including lake water and salt samples, in the presence of interferences like organic pollutants, inorganic ions, colloids, bio-organisms, and bisphenol A. This approach enables rapid detection of diverse microplastics in complex environmental samples.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"39 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144629878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their heterogeneous interactions with complex biological systems, especially at the single-cell level, are not fully understood yet. Conventional toxicity assessment methods are typically conducted on oversimplified in vitro models that fail to replicate actual physiological conditions, and measure collective responses across cell populations, obscuring differences among individual cells. To overcome these limitations, we utilized single-cell mass cytometry (CyTOF) to investigate individual cell responses to AgNP-induced stress, combined with a 3D alveolar tetra-culture model designed to better reflect the complexity of biological systems. Single-cell mass cytometry of a 3D alveolar model revealed heterogeneous, cell type–specific responses to AgNP exposure. Specifically, PMA-differentiated THP-1, A549 and EA.hy926 cells exhibited high AgNP association but limited cytotoxicity, indicating activation of stress-mitigation pathways, while THP-1 cells showed early inflammatory activation despite minimal AgNP association, suggesting indirect mechanism. Single-cell analysis and FlowSOM clustering revealed distinct subpopulations exhibiting diverse intracellular signaling profiles of inflammatory cytokines, anti-inflammatory mediators, and stress-response proteins, which unveiled common cellular responses and unique cell-type specific pathways determining cell fate (survival, transitional states, or apoptosis) upon AgNP exposure. This study introduces a novel framework for studying heterogeneous interactions of nanoparticles with complex biological system by integrating 3D alveolar tetra-culture model with single-cell mass cytometry analysis, enabling the dissection of nanoparticle-induced stress responses at an unprecedented level of detail. These insights have broad implications for nanotoxicology and nanomedicine, underscoring the need to account for cellular heterogeneity when evaluating nanoparticle-induced toxicity.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"14 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144629489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the ability of the RHIZOtest method, a standardized soil-plant exposure system, in providing a high-throughput testing platform for investigating NP phytoavailability. As a proof of concept, tomato plants were exposed to artificial soil spiked with model NP at concentrations of 400 and 4,000 mg kg-1 dm. Palladium(Pd)-doped Polystyrene Particles (PS-P) (Z-average diameter 210 nm, Surface Charge Zeta Potential -45.20±032 mV, polydispersity index 0.1, Pd doping ratio of 0.295% w/w Pd to PS-P) were used as surrogates for NPs. Pd content was measured as a proxy for quantifying PS-P uptake. After eight days exposure, Pd was detected in both roots and shoots of plants grown on both spiked soils, confirming PS-P uptake and translocation. On average, 5±1% of the spiked PS-P were taken up by the plants across spiking levels. Root concentration factors varied slightly between the lower and higher levels (31±2% and 24±3%, respectively), while translocation factors remained similar (~25%). Root biomass was significantly reduced compared to controls, suggesting possible concentration-dependent PS-P rhizotoxicity. Notably, the limited variability in concentration values measured in roots (±11%) and shoots (±23%), along with near-complete mass balance recovery (97-100%), demonstrated the reliability of RHIZOtest in accurately and consistently quantifying NP uptake while accounting for rhizosphere processes.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"7 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144629502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is especially true for nanoforms and nano-enabled products, where guidance on the application of validated methods and tools for the assessment and management of safety and sustainability is still lacking. The SAbyNA Guidance Platform fills these gaps, integrating i) informative modules covering the needs of all stakeholder profiles (i.e., industry, consultants, RTOs, regulatory bodies) by guiding them in the choice of methods, models and tools for exposure and hazard assessment, as well as in the selection of specific Safe-by-Design interventions; and ii) assessment modules for a screening-level evaluation of environmental sustainability and costs, and for a screening and detailed safety assessment of nanoforms and nano-enabled products along their life cycle. The potential of this digital tool to support different stakeholders towards safer and more sustainable developments is demonstrated in a real case study: a nano-enabled 3D-printed vacuum cleaner plastic component with antistatic properties (single walled carbon nanotubes-polycarbonate composite parts). The paper shows how a user inputs data to perform a screening assessment on the additive manufacturing case study and the digital platform provides the user with some Safe-by-Design recommendations, such as reducing the fiber length or rigidity, or by changing process parameters to reduce emissions. Hazard, exposure, costs, sustainability and functionality case study data were added in the detailed assessment module of the Platform to check whether the implemented Safe-by-Design intervention was able to improve the safety profile of this nano-enabled product without affecting sustainability and functionality performances. The study also demonstrated the added value of using the SAbyNA Guidance tool at the early stage of the nano-enabled product development for the quantification and visualization of safety, sustainability, cost and functionality aspects of nano-enabled products and processes.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"92 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biocompatible and biodegradable nanoparticles (<em>i.e.</em> amorphous calcium phosphate, ACP) have been engineered to act as a carrier for the sustained delivery of the herbicide. The resulting nanocomposite (Btz-ACP) was characterized through complementary techniques, such as PXRD, FTIR, TEM, and elemental analysis, confirming the successful loading of Btz onto ACP nanoparticles and the subsequent pH-responsive release of the herbicide in aqueous media. Release kinetic constants of 0.11 h<small>⁻¹</small> and 0.2 h<small>⁻¹</small> were found at pH 7 and pH 4.5, respectively. We also found that the retention of Btz-ACP was increased in inert soils in comparison to the free herbicide, indicating its potential to mitigate groundwater contamination. This new nanoherbicide allows a significant reduction of herbicide dosage by up to 60% compared to the commercial product at the recommended dosage (1 kg ha<small>⁻¹</small>) to efficiently control the growth of <em>Sinapis alba</em> (white mustard). Notably, the most diluted Btz-ACP formulation (0.4 kg ha<small>⁻¹</small>) exhibited the highest weed control at 10 days post treatment (96.3 ± 8.8% mortality), outperforming all other tested treatments: commercial formulations (77.4 ± 24.5% of mortality at the recommended dose and 74.5 ± 20.1% at the reduced dose of 0.7 kg ha<small>⁻¹</small>) but also higher doses of Btz-ACP (0.6 kg ha<small>⁻¹</small>) (78.1 ± 18.9% of mortality) with an inverse concentration–efficiency relationship. This may be due to the reduction of nanoparticle aggregation at low dosages, thus favoring nanoparticle penetration through the leaves. Interestingly, despite the huge reduction of dosage, the herbicidal effect is still visible after 28 days post-treatment, avoiding the regrowth of the target plant. The results demonstrate that this new nanomaterial offers a very promising approach to sustainable agriculture with reduced environmental impact.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"34 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
