The synthesis of semiconductor nanoparticles is an expanding research area due to the potential applications in the development of nanotechnologies. Especially, biosynthesized nanoparticles have become an important branch of nanotechnology. In the present work, we describe a low-cost and simple procedure for biosynthesis of Zinc oxide nanoparticles (ZnO NPs) using Pyrus Pyrifolia leaf extract. ...

background: new treatment modalities are developed with the aim of escalating tumor absorbed dose and simultaneously sparing the normal structures. the use of nanotechnology in cancer treatment offers some possibilities including destroying cancer tumors with minimal damage to healthy tissues. zinc oxide nanoparticles (zno nps) are wide band gap semiconductors and seem to have a good effect on ...

BACKGROUND The insufficient understanding of unintended biological impacts from nanomaterials (NMs) represents a serious impediment to their use for scientific, technological, and medical applications. While previous studies have focused on understanding nanotoxicity effects mostly resulting from cellular internalization, recent work indicates that NMs may interfere with transmembrane transport...

OBJECTIVES The purpose of this study is to examine whether Hominis Placental pharmacopuncture solution (HPPS) combined with zinc-oxide nanoparticles (ZnO NP) activates RAW 264.7 cells. METHODS We soaked ZnO nanoparticles in the Hominis Placenta pharmacopuncture solution, thereby making a combined form (ZnO NP HPPS). The effect of ZnO NP HPPS on the intracellular reactive oxygen species (ROS) ...

Objective(s): Stress is a physiological response that can disrupt body elements homeostasis and lead to neurophysiological abnormality. This study has been investigated the serum and hippocampus Mg2+, Zn2+, Fe2+/3+ and Ca2+ level changes in two times after MgO NPs and ZnO NPs single injection following restraint stress in the male rat. Methods: Animals were divided into two main groups that eac...

In this paper, a green microwave-assisted combustion approach to synthesize ZnO-NPs using zinc nitrate and Citrullus colocynthis (L.) Schrad (fruit, seed and pulp) extracts as bio-fuels is reported. The structure, optical, and colloidal properties of the synthesized ZnO-NP samples were studied. Results illustrate that the morphology and particle size of the ZnO samples are different and depend ...

BACKGROUND AND OBJECTIVES Bacterial resistance to conventional antibiotics has become a widespread public health problem. The aim of this study was to investigate the influence of zinc oxide nanoparticles (ZnO NPs) on the antibacterial activity of several conventional antibiotics against Pseudomonas aeruginosa. MATERIALS AND METHODS ZnO NPs were prepared by solvothermal method and dispersed i...

here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (tea) and zinc acetate. the zno nano particles (nps) were formed and stabilized on the fabric surface by amine compound at 130 °c for 1 h. the synthesis of nano zno particles on the polyester fabric were confirmed by x-ray diffraction (xrd) pattern...

   Present study has comparatively investigated the effect of zinc oxide nanoparticles (ZnO NPs), ZnO bulk particles (BPs), and relevant metal ions (Zn2+) on the tissue culture of rapeseed (Brassica napus L.) to properly evaluate the impact of ZnO NPs on callus induction. For finding the best hormonal combination for inducing callus, hypocotyl explants were cultured on Murashige ...
