Overuse of chemicals results in soil degradation, water and environmental pollution, potential health risks in all living forms on the earth. Chemical fertilizers adversely affects the soil microbes, deteriorating soil quality by nutritional deficits, hence necessitating eco-friendly alternatives for fostering crop growth. Nanotechnology provides innovative solutions, impacting every stage from seed germination to storage, promoting sustainable farming practices. Among these advancements, silica nanoparticles (SiNp) have emerged as a promising candidate for enhancing plant growth and development. To explore this potential, we report a novel green synthesis of Triphala medited silica nanoparticles (TpSiNps) by using aqueous fruit extract from a blend of <i>Terminalia bellirica, Emblica officinalis,</i> and <i>Terminalia chebula</i> fruits (Triphala)<i>,</i> marking the first green synthesis of silica nanoparticles using a polyherbal formulation. The synthesized TpSiNps were characterized as stable, heterogeneous, and nano-coarse. <i>Vigna radiata</i>, a widely cultivated and nutritionally rich legume of agricultural significance, posed as a plant model to evaluate the potential of TpSiNps in promoting plant growth. Seedlings were treated with TpSiNps (1 ppm, 5 ppm, and 10 ppm) and analysed for seed germination, growth, and biochemical constituents. Experimental findings indicate that at 10 ppm, TpSiNps improved seed germination by ~ 45% and enhanced growth parameters, with shoot length by ~ 107%, root length by ~ 58%, and fresh biomass by ~ 59% in tested <i>Vigna radiata</i>. Furthermore, increased levels of bio constituents, including carbohydrates (~ 21%), proteins (~ 8%), tryptophan (~ 10%), chlorophyll (~ 8%), and carotenoids (~ 12%) suggest a stimulatory effect of TpSiNps on the metabolic processes of <i>Vigna radiata</i>. These results highlight TpSiNps's potential as a viable green nanotechnology solution for addressing agricultural challenges and ensuring food security.</p></div>","PeriodicalId":51136,"journal":{"name":"Nanoscale Research Letters","volume":"20 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s11671-025-04268-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of the high price of chitosan, it’s badly needed to find another polymer that is cheap and at the same time effective. So, starch as a natural polysaccharide was used as a polymer in nanopesticide formulations. In this work, some insecticides (acetamiprid, chlorfenapyr, emamectin benzoate, etofenprox, imidacloprid and indoxacarb) were loaded on both nanochitosan and nanostarch. By using zeta potential and particle size, the nanoparticles of all tested insecticides loaded on chitosan were 287.5, 99.9, 78.8, 696.6, 685.9 and 295.3 nm for acetamiprid, chlorfenapyr, emamectin benzoate, etofenprox, imidacloprid and indoxacarb, respectively. The corresponding results with starch were 176.1, 342.0, 647.8, 178.8, 809.1, and 68.7 nm, respectively. The zeta potential (charges) of all tested nanoformulations that loaded on chitosan were 0.9, 6.7, 4.2, 9.3, 11.1 and 4.8 mV for acetamiprid, chlorfenapyr, emamectin benzoate, etofenprox, imidacloprid and indoxacarb, respectively, while loading on starch was 4.7, 7.5, 12.9, 19.6, 28.5 and 8.6 mV, respectively. The loading capacity of all tested insecticides was 59.5, 50.6, 44.6, 55.6, 41.1 and 53.2%, respectively, for the chitosan nanocarrier; and 45.8, 46.3, 31.9, 33.7, 35.1 and 51.7%, respectively, for the starch nanocarrier. The obtained results indicated that starch was very effective as a polymer compared with chitosan. The charges of nanostarch were more than those of nanochitosan. This means that the nanostarch formulation was more homogenous than nanochitosan. These results found that starch is a very cheap material, stable, biodegradability, and ease of preparation compared with chitosan.

This study explores light-mediated strategies to optimize cargo encapsulation into PDEVs while preserving structural integrity. Leveraging the intrinsic photosensitizing properties of PDEVs, light irradiation (LED) triggered reactive oxygen species (ROS) generation, including superoxide anions and singlet oxygen, which transiently enhanced membrane permeability for controlled drug loading. Using FITC-dextran (70 kDa) as a model cargo, we optimized light-induced loading efficiency, achieving a peak (~ 80%) at 10 min of irradiation. Prolonged exposure (15 min) reduced efficiency (~ 50%), likely due to excessive ROS-induced membrane destabilization. The optimal PDEVs-to-cargo ratio (1:30) ensured maximal loading while maintaining stability over 30 days. Lipid peroxidation analysis further confirmed ROS-induced membrane modifications through malondialdehyde (MDA) accumulation. These findings demonstrate that PLDENs (Pueraria lobate-derived exosomes-like nanovesicles) function as light-responsive nanocarriers, balancing ROS-mediated permeability enhancement with structural integrity.

Among them, polylactic acid (PLA) and polypropylene carbonate (PPC), as renewable polymers, have a number of advantages but also have their respective limitations, and their blending is expected to complement each other’s strengths. In addition, the addition of appropriate compatibilizers such as calcium carbonate (CaCO₃) nanoparticles can improve performance. Considering the high cost and time consuming experimental studies, the present study was carried out using molecular dynamics (MD) simulations for PLA/PPC/CaCO₃ bio-nanocomposites with different mass fractions (0–5 wt%), with samples denoted by ACCax (0 ≤ x ≤ 5). FFV calculations revealed that CaCO₃ nanoparticles interacted with PLA and PPC chains and changed the distribution and folding of polymer chains; the <i>T</i>_<i>g</i> results showed that a small amount of CaCO₃ added to the composites shifted the <i>T</i>_<i>g</i> towards higher temperatures, which improved the compatibility of the two polymer chains; and the inter-component interaction energy results showed that, for the ACCax nanocomposites, the filling threshold of CaCO₃ in PLA/PPC blends was 3 wt%. The radial distribution function (RDF) results indicated that the interactions between components were hydrogen bonding and van der Waals force, and the strength depended on the nanoparticle content. The interaction between PLA and CaCO₃ was mainly hydrogen bonding, and the interaction between PPC and CaCO₃ was mainly van der Waals force, and the comparative analysis showed that nanoparticles in the samples containing 3 wt% of CaCO₃ interacted more strongly with the PLA chain. Comparative analysis showed that the nanoparticles in the sample containing 3 wt% CaCO₃ interacted more strongly with the PLA chains, and the order of the RDF peaks in each sample was ACCa3 &gt; ACCa2 &gt; ACCa1 &gt; ACCa5. The analysis of the water adsorption sites on the composites, the energy distribution, and the mean square displacements (MSD) of water in the different samples, as well as the diffusion coefficients, showed that the filler with 3 wt% of CaCO₃ had a better dispersibility in the matrix, the free volume of the system was reduced, and the diffusion channel of water vapour was widened, which led to promising success in the field of biodegradable membranes for food packaging or waterproofing for agriculture. In conclusion, MD simulation is a powerful tool for predicting the gas permeability of polymers, blends and nanocomposites.</p></div>","PeriodicalId":51136,"journal":{"name":"Nanoscale Research Letters","volume":"20 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s11671-025-04223-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improved drug delivery has therefore recently been achieved through the versatile physico-chemical properties of nanocrystals (NCs) in targeted cancer therapies. Here, nanocrystalization was used with xanthatin, a not highly water-soluble natural sesquiterpene lactone compound that possesses anti-tumour properties and which was recently investigated for potential use in the treatment of cancer and autoimmune diseases. Given that tumour-promoting inflammation is a hallmark of colorectal cancer (CRC), and that epidemiological studies associated inflammatory biomarkers to CRC poor prognosis and therapy resistance, the anti-inflammatory properties of xanthatin NCs were assessed in 2D monolayers and in 3D spheroids of a human HT29 CRC cell model. The 3D spheroids being a model recapitulating a cancer stem cells and chemoresistant phenotype. HT29 2D monolayer cell response was first tested against four pro-inflammatory inducers including phorbol-12-myristate-13-acetate, tumour necrosis factor alpha (TNFα), transforming growth factor beta, and Concanavalin A. Of these inducers, HT29 cell response to TNFα resulted in the most elevated expression of cyclooxygenase (COX)-2 which was prevented by commercial xanthatin along with the phosphorylation of the extracellular signal-regulated kinase 1/2 and of IkappaB (IκB). Alteration of 3D spheroids formation and of the inflammatory/immunity transcriptomic signature was also found better altered by xanthatin NCs in comparison to commercial xanthatin and the isolated molecule. Collectively, our data indicate that xanthatin nanocrystallization did not alter the potential in vitro anti-inflammatory and anticancer properties of xanthatin against a 3D CRC chemoresistance cellular model.

This paper presents a composite model that combines a power function with a Gaussian function to calculate the PSF, where the forward scattering component is described by a power function and the backscattering component is represented by a Gaussian function. This approach ensures high accuracy of the PSF while simultaneously reducing computational complexity. Experimental validation was conducted using the commercial software BEAMER developed by GenISys GmbH, where the PSF curve obtained from this model was employed for PEC, resulting in a well-defined hydrogen silsesquioxane (HSQ) zone plate structure with an outer ring width of 30 nm. Comparative experiments showed that the composite model outperforms traditional Monte Carlo and double Gaussian models in terms of correction performance for the zone plate structure.
