Residual-Solvent-Induced Morphological Transformation by Intense Pulsed Light on Spin-Coated and Inkjet-Printed ZnO NP Films for Quantum-Dot Light-Emitting Diodes.

ACS Applied Materials and Interfaces, 2021
It was demonstrated through a comparison between the spin-coated and inkjet-printed quantum-dot light-emitting diodes' (QLED) performance analysis outcomes that the annealing temperature of a zinc oxide nanoparticle (ZnO NP) electron transport layer (ETL)

Behaviour and fate of Ag-NPs, TiO2-NPs and ZnO-NPs in the human gastrointestinal tract: Biopersistence rate evaluation

Food and Chemical Toxicology, 2023
This study aims to provide information on the behaviour and biopersistence rate (BP) of metallic nanoparticles (Ag-NPs, TiO2-NPs, ZnO-NPs) naturally occurring in canned seafood and subjected to static in vitro digestion. Single particle ICP-MS analysis was performed to determine NPs distribution and concentrations in oral, gastric, and intestinal ...

Determination of the relative contribution of the non-dissolved fraction of ZnO NP on membrane permeability and cytotoxicity

Inhalation Toxicology, 2020
Background: While the role of lysosomal membrane permeabilization (LMP) in NP-induced inflammatory responses has been recognized, the underlying mechanism of LMP is still unclear.

Assessment of ZnO-NPs toxicity in maize: An integrative microRNAomic approach

Chemosphere, 2020
Rapid expansion of nanotechnology and indiscriminate discharge of metal oxide nanoparticles (NPs) into the environment pose a serious hazard to the ecological receptors including plants. To better understand the role of miRNAs in ZnO-NPs stress adaptation, two small RNA libraries were prepared from control and ZnO-NPs (800 ppm,

Characterisation of ZnO NPs as contrast agents for MWI

2017 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2017
This study presents the examination of zinc oxide (ZnO) nanoparticles (NPs) as potential contrast agents for microwave imaging (MWI). Polyethylene Glycol (PEG) with varying molecular weights (Mw) have been used to coat NPs. Characterisation of the colloidal dispersions have been recorded using Atomic Force Microscopy (AFM), Scanning Electron Microscopy
