In this study, the extract of coffee powder for green synthesis of zinc oxide nanoparticles has been used because it is compatibility with the environment and it does not produce any toxic substances in the reaction. Then, the interaction of zinc oxide nanoparticles with calf thymus DNA with various spectroscopic methods such as UV-Visible, fluorescence and circular dichroism (CD) techniques wa...
whit the extension of nanotechnology and materials engeneering, various nanoparticles are produced that have new characteristics but the toxic effects of them is still unknown in most of materials. nowadays metal oxide nanoparticales are widely used in indusery and other fields. this study was conducted goldfish with the average weigh of 3±0.5 gr and owerag length of 7±0.5 cm nd four cares of z...
ارزیابی اثر ضد میکروبی نانوذرات بیوژنیک اکسید روی بر دو سویه استاندارد باکتریایی گرم منفی و گرم مثبت
Background: Nanoparticles are particles that have at least one dimension between 1 and 100 nanometers. Nanoparticles are a new generation of antimicrobial agents. Nanoparticles with antimicrobial activity, especially as a new class of biomedical materials for use in increasing the level of public health in daily life have emerged. Zinc oxide nanoparticles have attracted a great attention due t...
In this paper, a biosensor has been fabricated using ZnO nanorods and nanoparticles to detect different concentrations of the E. coli bacteria. The innovation of this paper lies in design and fabrication of the resistive type E Coli bacteria sensor. To make this biosensors, printed circuit board based electrodes are designed and made in an interdigitated shape. Both hydrothermal and drop cast m...
The interaction of copper oxide nanoparticles and copper ions and proteinase K from Tritirachium album Limber has been investigated employing UV spectroscopy and kinetics measurements. The aim of this study was to evaluate the effect of nanoparticles of CuO for proteinase K. In this paper we compare the effect of copper oxide nanoparticles with the effect of copper ions on proteinase K sta...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Nowadays, the entrance of nanoparticles into high seas has led to toxic effects on aquatic organisms. Copper oxide nanoparticles is among the most widely used nanoparticles. The presence of these nanoparticles in the aquatic environments cause new environmental problems, which indicate the necessity of the examination of the effects of these nanoparticles on the aquatic organisms. The alfalfa p...
Submit Manuscript | http://medcraveonline.com treating these and other bacterial infections currently exist; there is still an essential need for new and improved approaches for bacterial destruction. Nanomedicine is one approach to overcome challenges of conventional drug delivery systems based on the development and fabrication of nanostructures. Various types of nanoparticulate systems have ...
Plant-mediated synthesis of metal oxide nanoparticles is a promising alternative to the traditional method of physical and chemical synthesis. In this paper, we report the green synthesis of zinc oxide nanoparticles (ZnONPs) by a biological method. During the study, Zinc oxide nanoparticles were synthesized by Allium sativum skin (garlic skin) extract. Formation of zinc oxide nanoparticles has ...
objective(s):iron oxide nanoparticles have found prevalent applications in various fields including drug delivery, cell separation and as contrast agents. super paramagnetic iron oxide (spio) nanoparticles allow researchers and clinicians to enhance the tissue contrast of an area of interest by increasing the relaxation rate of water. in this study, we evaluate the dependency of hydrodynamic si...
