Graphene oxide (GO) is a promising and remarkable nanomaterial that exhibits antimicrobial activity due to its specific surface–interface interactions. In the present work, for first time, we have reported antibacterial of GO-coated surfaces prepared by two different methods (Hummers' improved, i.e., GOH GOI) against bacterial biofilm formation. The toxicity deposited was investigated both Gram-negative (Escherichia coli) Gram-positive (Staphylococcus aureus) models bacteria. mechanism...
In this work, the fabrication of MoS2-Polyaniline (PANI) nanocomposites, by in situ polymerization, has been described and its application as a photocatalyst for degradation organic pollutants such methylene blue (MB) 4-chlorophenol (4-CP), reported. The disadvantages MoS2 poor electronic conductivity agglomeration between nanosheets, was overcome intercalating 2D layers with 1D conducting polymer, Polyaniline (PANI). composite material characterised SEM, TEM, BET, XRD, FTIR, UV–Vis...
Copper oxide (CuO) nanoparticles (NPs) are known to trigger cytotoxicity in a variety of cell models, but the mechanism death remains unknown. Here we addressed macrophages exposed CuO NPs versus copper chloride (CuCl2).The mouse macrophage line RAW264.7 was used as an vitro model. Particle uptake and cellular dose Cu were investigated by transmission electron microscopy (TEM) inductively coupled plasma mass spectrometry (ICP-MS), respectively. The deposition lysosomes isolated from also...
The growing nanoparticulate pollution (e.g. engineered nanoparticles (NPs) or nanoplastics) has been shown to pose potential threats human health. In particular, sensitive populations such as pregnant women and their unborn children need be protected from harmful environmental exposures. However, developmental toxicity prenatal exposure particles is not yet well studied despite evidence of particle accumulation in placenta. Our study aimed investigate how copper oxide NPs (CuO NPs; 10–20 nm)...
The neurotoxicity of hard metal-based nanoparticles (NPs) remains poorly understood. Here, we deployed the human neuroblastoma cell line SH-SY5Y differentiated or not into dopaminergic- and cholinergic-like neurons to study impact tungsten carbide (WC) NPs, WC NPs sintered with cobalt (Co), Co versus soluble CoCl2. salt triggered a dose-dependent cytotoxicity an increase in cytosolic calcium, lipid peroxidation, depletion glutathione (GSH). also suppressed peroxidase 4 (GPX4) mRNA protein...
In the current study, we have developed a lightweight nanocomposite biofertilizer (NCB) consisting of physical mixture acylated homoserine lactone (AHL)-coated Fe-carbon nanofibers (Fe-CNFs) and bacterial (Panebacillus polymyxa) endospores immobilized in activated carbon beads. AHL/Fe-CNF is translocated to plants via apoplastic movement through roots shoots leaves, while are retained soil, augmenting plant growth siderophore indole acetic acid production. We tested NCB on leguminous (Cicer...
Abstract There is an urgent need to apply effective, data-driven approaches reliably predict engineered nanomaterial (ENM) toxicity. Here we introduce a predictive computational framework based on the molecular and phenotypic effects of large panel ENMs across multiple in vitro vivo models. Our methodology allows for grouping multi-omics combined with robust toxicity tests. Importantly, identify mRNA-based markers extensively replicate them independent datasets. We find that models...
Exposure to nanoparticles (NPs) in pregnancy is increasingly linked adverse effects on embryo-fetal development and health later life. However, the developmental toxicity mechanisms of NPs are largely unknown, particular potential placental secretome, which orchestrates many processes pivotal for success. This study demonstrates extensive material- stage-specific deregulation signaling from a single exposure human explants physiologically relevant concentrations engineered (silica (SiO
The increasing applications of engineered nanomaterials (ENMs) in consumer products warrant a careful evaluation their trophic transfer and consequent ecological impact. In the present study, laboratory scale aquatic microbial food chain was established using bacteria (Escherichia coli (E. coli)) as prey ciliated protozoan (Paramecium caudatum) predator organism to determine impact cadmium telluride quantum dots (CdTe QDs). We observed that 29% bacterivory potential paramecium lost,...
AHL/Fe-CNF nanocomposites were effective in increasing germination rate and plant growth as well developing resistance towards biotic abiotic stresses.
Carbon nanotubes (CNTs) have been extensively investigated, and several studies shown that multi-walled CNTs can trigger inflammation fibrosis in animal models. However, while neutrophils are involved inflammation, most vitro addressed macrophages. Here we explored the impact of three MWCNTs with varying morphology (i.e. long rigid versus short and/or tangled) on primary human macrophages macrophage-differentiated THP-1 cells neutrophil-differentiated HL-60 cells. We found triggered...
Abstract Numerous studies have addressed the biological impact of graphene‐based materials including graphene oxide (GO), yet few focused on long‐term effects. Here, RNA sequencing is utilized to unearth responses human lung cells GO. To this end, BEAS‐2B cell line derived from normal bronchial epithelium subjected repeated, low‐dose exposures GO (1 or 5 µg mL −1 ) for 28 days equivalent, cumulative amount 48 h. Then, samples are analyzed by using NovaSeq 6000 system followed pathway...

Abstract Nano titanium dioxide (nTiO 2 ) is the most abundantly released engineered nanomaterial (ENM) in aquatic environments. Therefore, it prudent to assess its fate and effects on lower trophic-level organisms food chain. A predator-and-prey-based laboratory microcosm was established using Paramecium caudatum Escherichia coli evaluate of nTiO . The surface interaction with E. significantly increased after addition into microcosm. This favoured hetero-agglomeration co-sedimentation extent...
