Controllable fabrication of Ag-NP-decorated porous ZnO nanosheet arrays with superhydrophobic properties for high performance SERS detection of explosives

, 2020
An efficient hydrophobic condensation surface was developed and used as an ultrasensitive surface-enhanced Raman scattering (SERS) sensor. The sensors were based on ZnO–Ag hybrid mesoporous nanosheets (MNSs) grafted on ordered Si micropillar arrays for ...

Oxidative stress, genotoxic effects, and other damages caused by chronic exposure to silver nanoparticles (ag NPs) and zinc oxide nanoparticles (ZnO NPs), and their mixtures in zebrafish (Danio rerio).

Toxicology and Applied Pharmacology, 2023
This study assessed the oxidative stress impacts of Ag NPs and ZnO NPs and their mixtures in zebrafish (Danio rerio). Zebrafish were exposed to sublethal concentrations of each NP and a mixture for 28 days followed by a 28-day recovery period (without NP

A review of cardiovascular toxicity of TiO2, ZnO and Ag nanoparticles (NPs)

BioMetals, 2018
To ensure the safe use of nanoparticles (NPs) in modern society, it is necessary and urgent to assess the potential toxicity of NPs. Cardiovascular system is required for the systemic distribution of NPs entering circulation. Therefore, the adverse cardiovascular effects of NPs have gained extensive research interests.

Sustainable synthesis of biogenic ZnO NPs for mitigation of emerging pollutants and pathogens

Environmental Research, 2023
Groundwater pollution is mostly caused by overuse of fertilizers, pesticides, contemporary agricultural practices, anthropogenic activities, home waste disposal, and the rapid expansion of the chemical industry. Drinking tainted water on a regular basis can have detrimental consequences on human health as well on environment.

Particle Size Determines the Phytotoxicity of ZnO Nanoparticles in Rice (Oryza sativa L.) Revealed by Spatial Imaging Techniques.

Environmental Science and Technology, 2023
To understand the nanotoxicity effects on plants, it is necessary to systematically study the distribution of NPs in vivo. Herein, elemental and particle-imaging techniques were used to unravel the size effects of ZnO NPs on phytotoxicity.

Preparation and characterization of PVA/arginine chitosan/ZnO NPs composite films

International Journal of Biological Macromolecules, 2023
In this study, arginineated chitosan (ACS) was used as a soft brain membrane and chelating agent to synthesize ACS-ZnO NPs, and then ACS and ACS-ZnO NPs were added to a polyvinyl alcohol (PVA) matrix as an antimicrobial agent to form films by casting. The formation and structural morphology of ACS and ACS-ZnO NPs were investigated by applying FTIR, 1H ...

The effects of baicalein or baicalin on the colloidal stability of ZnO nanoparticles (NPs) and toxicity of NPs to Caco-2 cells

Toxicology Mechanisms and Methods, 2017
Recent study suggested that the presence of phytochemicals in food could interact with nanoparticles (NPs) and consequently reduce the toxicity of NPs, which has been attributed to the antioxidant properties of phytochemicals. In this study, we investigated the interactions between ZnO NPs and two flavonoids baicalein (Ba) or baicalin (Bn) as well as ...

The role of ZnO NPs loaded with metformin NPs in kidney histological changes in Rats with Diabetic Nephropathy

2023
Abstract Metformin nanoparticles were created using a microemulsions method. Metformin nanoparticles were identified using a transmission electron microscope (TEM), which showed that their average size is 27.5 nm. An method called photo-irradiation was used to create ZnO nanoparticles.
