In this study, the effects of treatment with Ag, Au, Cu, Pd, CeO2, CuO, TiO2 and ZnO nanoparticles (NPs) on plant secondary metabolism were tested using an untargeted metabolomic approach in cell suspension cultures Hypericum perforatum L. Variations accumulation metabolites observed after exposure to NPs. Overall, number compounds increased by metal NPs was higher than that oxides. Among oxide...

The main mechanism of toxicity for fast-dissolving nanoparticles (NPs) is relatively simple as it originates from the intrinsic toxicity of their constituent elements rather than complicated surface reactivity. However, there is little information about the compared toxicity of fast-dissolving NP and its constituent ion, which is essential for understanding the mechanism of NP toxicity and the ...

The external and interlamellar spaces of montmorilonite (MMT) were used as solid support for synthesis of CuO nanoparticles (NPs) at room temperature by the chemical reduction method. In this project, Copper Nitrate plus water (Cu(NO3)2. xH2O) and Sodium Hydroxide (NaOH) were used as Copper precursor and reducing agent respectively. Then, MMT/Cu2+ nanocomposites were stabilized with different r...

Abstract Brassica is one of the crops sensitive to low copper supply, leading Alternaria blight. The present study reflects synthesis myco-derived oxide (M-CuO) nanoparticles (NPs) from Trichoderma asperellum and investigates their effect against blight in two soil types, alluvial calcareous. Foliar applications different treatments were used treat plants: T1 ([email protected]%), T2 (propiconazole@...

In this study, successful synthesis of ZnO nanoparticles (NPs), CuO NPs, and ZnO/CuO nanocomposite through an eco-friendly method using Corriandrum sativum leaf extract as a capping agent is reported. Using XRD, FTIR, UV-Vis, SEM techniques, the synthesized materials were characterized for structural analysis, functional groups identification, spectroscopic measurements, morphological analysis....

Recent nanotechnological advances suggest that metal oxide nanoparticles (NPs) have been expected to be used in various fields, ranging from catalysis and opto-electronic materials to sensors, environmental remediation, and biomedicine. However, the growing use of NPs has led to their release into environment and the toxicity of metal oxide NPs on organisms has become a concern to both the publ...

We report the green chemistry reduction approach method for synthesis of Manganese Oxide nanoparticles (MnO NPs), Copper (CuO NPs) and Manganese-doped (Mn-doped CuO Nps). Aqueous extract from seeds was used as reducing capping agents. The detailed crystal structure analysis investigated; crystallite size, crystallinity, morphological index, x-ray density, bulk specific surface area, porosity, L...
