Nanoparticles, generally considered as particle with a size of upto 100nm, exhibit completely new or improved properties as compared to the larger particles of the bulk material that they are composed of based on specific characteristics such as size, distribution and morphology. In this study ZnO nanoparticle was synthesized by a simple and easy chemical method from ZnCl2. The synthesized nano...

The alteration in intracellular Zn2+ homeostasis is attributed to the generation of intracellular reactive oxygen species, which subsequently results in oxidative damage of organelles and cell apoptosis. In this work, the neurotoxic effects of ZnO hierarchical architectures (nanoparticles and microspheres, the prism-like and flower-like structures) were evaluated through the 3-(4, 5-dimethylthi...

Engineered zinc oxide nanoparticles (ZnO-NPs) are currently being produced in high tonnage. Exposure to ZnO-NPs presents potential risks to cardiovascular system. Thus far, the toxicological effects of ZnO-NPs on cardiovascular system have not been well characterized. In this study, human coronary artery endothelial cells (HCAECs) were exposed to ZnO-NPs directly or indirectly using a transwell...

Pectin–ZnO nanocomposite was prepared in the aqueous solution condition at room temperature. The Fourier transform infrared, X-ray diffraction, and transmission electron microscope (TEM) measurements confirmed the nanoscaled structure of pectin–ZnO composite. According to the TEM observation, the average composite granules size was about 150 nm and the embedded ZnO nanoparticles were uniform wi...

Extremely small nanomaterials with dimensions roughly less than 100 nanometers (nm), can demonstrate atom-like behaviors resulting from higher surface energy because of their large surface area and broad band gap between valence and conduction band when nanomaterials are divided into near atomic size.1 ZnO nanopowders are basic metal oxide particles with interesting properties and wide applicat...

ZnO nanoparticles were synthesized via novel Sol-gel route. The effects of pH variation as well as ageing were studied. The nanoparticles were synthesized with two different pH levels viz. pH 7 and pH 10. It was found that the size of the nanoparticles increased from 19 to 39.6 nm with increase in pH level from 7 to 10. Further the effect of ageing on the ZnO nanoparticles was studied. It was f...

The antibacterial and antibiofilm activity of chemically synthesized pure and Cu doped ZnO nanoparticles against marine biofilm forming bacteria has been reported for the first time. The synthesized nanoparticles were characterized using PXRD, FTIR and SEM which confirmed the formation of phase pure nanostructured zinc oxides. The antibacterial and antibiofilm activities of the synthesized nano...

Quantum dot-sensitized solar cells (QDSCs) constructed using cascade CdS/CdSe sensitizers and the novel tetrapod-like ZnO nanoparticles have been fabricated. The cascade co-sensitized QDSCs manifested good electron transfer dynamics and overall power conversion efficiency, compared to single CdS- or CdSe-sensitized cells. The preliminary CdS layer is not only energetically favorable to electron...
