Uptake and translocation of manufactured nanoparticles (NPs) in plants have drawn much attention due to their potential toxicity the environment, including food webs. In this paper, xylem phloem based transport CeO2 NPs hydroponic cucumber was investigated using a split-root system. One half root system treated with 200 or 2000 mg/L for 3 days, whereas other remained untreated, both halves sharing same aerial part. The quantitative distribution speciation Ce different plant tissues sap were...
Different plant species respond differently to nCeO<sub>2</sub> under different culturing conditions: for some, deficiency of P enhances the accumulation Ce (mainly Ce<sup>3+</sup>) and phytotoxicity.
The physiochemical properties of nanoparticles (NPs), including surface charge, will affect their uptake, transformation, translocation, and final fate in the environment. In this study, we compared phytoxoxicity transport behaviors nano CeO2 (nCeO2) functionalized with positively charged (Cs-nCeO2) negatively (PAA-nCeO2) coatings. Cucumber seedlings were hydroponically exposed to 0–1000 mg/L Cs-nCeO2 PAA-nCeO2 for 14 days contents, distribution, transformation Ce plants analyzed using...
The trophic transfer and transformation of CeO2 nanoparticles (NPs) through a simulated terrestrial food chain were investigated using radiotracer technique X-ray absorption near edge structure (XANES). Radioactive 141CeO2 NPs applied to head lettuce (Lactuca sativa), treated via root exposure in its potting soil (5.5 or 11 mg/plant) for 30 days foliar (7.2 mg/plant, with half the leaves other not) 7 days. Subsequently, two groups land snails (Achatina fulica) exposed 141Ce either direct...
The mechanism of graphene-based nanomaterial (GBM)-induced phytotoxicity and its association with the GBM physicochemical properties are not yet fully understood. present study compared effects graphene oxide (GO) reduced GO (rGO) on rice seedling growth under hydroponic conditions for 3 weeks. at 100 250 mg/L shoot biomass (by 25 34%, respectively) elongation 17 43%, caused oxidative damage, while rGO exhibited no overt effect except enhancement antioxidant enzyme activities, suggesting...
MoS2-ZnO composites were synthesized using a solution-based method. The scanning electron microscopy and transmission analysis demonstrated that ZnO nanoparticles with size of about 4.5 nm coated on the basal surface MoS2 nanosheets an expanded spacing (002) plane. composite-based poly(methyl methacrylate) (PMMA) organic glasses (MoS2-ZnO-PMMA glasses) prepared through polymerization process. nonlinear absorption (NLA), scattering (NLS), optical limiting (OL) properties MoS2-ZnO-PMMA...
Life is inherently heterogeneous, and visualizing this heterogeneity in the spatial distribution of biometals offers valuable insights into various biological processes. While biometal mapping provides superior resolution compared to other bioanalytical techniques, it alone cannot fully explain functional roles health disease. In study, we introduced a novel method using specially designed sample grids facilitate beam-, X-ray-, ion-beam-based imaging on same tissue section. This innovative...
Abstract The release of metal ions may play an important role in toxicity metal‐based nanoparticles. In this report, a life cycle study is carried out greenhouse, to compare the effects ceria nanoparticles (NPs) and Ce 3+ at 0, 50, 100, 200 mg kg −1 on plant growth, biological physiological parameters, nutritional value soil‐grown common bean plants. Ceria NPs have tendency negatively affect photosynthesis, but effect not statistically significant. ionic treatments result increases 1.25‐,...
Epigallocatechin-3-gallate (EGCG), the most abundant tea polyphenol, possesses excellent anti-inflammation properties. Emerging studies proved its potent potential as an immune checkpoint (ICP) inhibitor for anticancer therapy. However, low bioavailability of EGCG reduces treatment efficiency. In this work EGCG-based nanomedicine EGCG–ZIF-8@PDA–PEG (EZP) was developed via coordination between ZIF-8 MOF and EGCG, followed by polydopamine PEG functionalization efficient tumor-targeting...
Despite the success of immuno-oncology in clinical settings, therapeutic efficacy is lower than expectation due to immunosuppressive inflammatory tumor microenvironment (TME) and lack functional lymphocytes caused by exhaustion. To enhance immuno-oncotherapy, a synergistic strategy should be used that can effectively improve TME increase infiltration cytotoxic T (CTLs). Herein, hypoxia-responsive nanogel (NG) developed delivery penetration diacerein (-)-epigallocatechin gallate (EGCG)...
The development of nanotechnology has transformed many cutting-edge studies related to single-molecule analysis into nanoparticle (NP) detection with a single-NP sensitivity and ultrahigh resolution. While laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) been successful in quantifying tracking NPs, its quantitative calibration remains major challenge due the lack suitable standards uncertain matrix effects. Herein, we frame new approach prepare via precise synthesis...
Nitrogen plays a vital role in the growth, development and nutritional quality of Chinese chive, which is an important leafy vegetable. The effects improved Hoagland nutrient solutions on physiological characteristics three chive cultivars (Saisong, Pingjiu No. 4 8) were investigated by modulating ratio nitrite nitrogen (NO3--N) to ammonia (NH4+-N). Improved with NO3--N NH4+-N ratios 50:50 75:25 could effectively promote accumulation soluble protein, sugar, vitamin C proline; decrease...
The time-course association of soil physicochemical properties and fate CeO2 nanoparticles (NPs) is not well understood. This study for the first time investigated dissolution retention NPs (<25 nm) during short-term (6 h) long-term (30 d) aging processes with dynamic redox conditions. Under additional reductant-induced initial reductive condition, theoretically, up to 220‰ Ce(IV) was temporarily reductively dissolved within 10 min, accompanied by a slow process (180 min) Ce species in...
