influenza is one of the most important viral diseases that is common among the birds and the mammalsand is caused by specific viruses that belong to the orthomyxoviridae family. migratory aquatic birds arethe reservoir of the disease and there is a likelihood of the disease in any region. there are differentmethods for detecting the avian influenza, but by the point of detection rates, the elis...

We use plasmon coupling between individual gold nanoparticle labels to monitor subdiffraction limit distances in live cell nanoparticle tracking experiments. While the resolving power of our optical microscope is limited to approximately 500 nm, we improve this by more than an order of magnitude by detecting plasmon coupling between individual gold nanoparticle labels using a ratiometric detect...

BACKGROUND This follow-up study aims to determine the physical parameters which govern the differential radiosensitization capacity of two tumor cell lines and one immortalized normal cell line to 1.9 nm gold nanoparticles. In addition to comparing the uptake potential, localization, and cytotoxicity of 1.9 nm gold nanoparticles, the current study also draws on comparisons between nanoparticle ...

background and objectives according to islamic doctrines, the use of gold for men has been banned. in general, any advised subject in islam is useful for the body and what has definitely forbidden for a man is definitely harmful for him although its reasons have not been exactly specified. however, muslims believe that there is certainly a sound reason behind this prohibition. this issue was st...

cell-based biosensors have become a research hotspot in biosensors and bioelectronics fields. the main feature of cell-based biosensors is the immobilization of living cell on the surface of transducers. different types of polymers which are used as scaffolds for cell growth should be biocompatible and have reactive functional groups for further attachment of biomolecules. in this work, the cel...

Background and Aims: Gold nanoparticles have potential applications in the areas of medicine, target drug delivery, cancer diagnosis and therapy, electronic, etc. Recently, biological system is considered as an environmental friendly method for synthesis of stable nanoparticles. Methods: We demonstrated a biological system for formation of stable gold nanoparticle by using Cupriavidus necator w...

The use of gold nanoparticle as an anti-infective agent has been proposed for years[1]. However, many reports mention for its ability counteracting bacteria. Its property against virus has never been systematically evaluated. Here, the authors performed a preliminary in vitro study to assess the effect of gold nanoparticle on viral load of hepatitis C virus (HCV). The standard gold nanoparticle...
