We review recent work on DNA-linked gold nanoparticle assemblies. The synthesis, properties, and phase behavior of such DNA-gold nanoparticle assemblies are described. These nanoparticle assemblies have strong optical extinction in the ultraviolet and visible light regions; hence, the technique is used to study the kinetics and phase transitions of DNA-gold nanoparticle assemblies. The melting ...

Multifunctional hybrid-design nanomaterials appear to be a promising route to meet the current therapeutics needs required for efficient cancer treatment. Herein, two efficient heat nano-generators were combined into a multifunctional single nanohybrid (a multi-core iron oxide nanoparticle optimized for magnetic hyperthermia, and a gold branched shell with tunable plasmonic properties in the NI...

molecular dynamics simulation has been performed to analyze the effect of the presence of gold nanoparticle on dynamics of kob-anderson binary lennard-jones (blj) mixture upon supercooling within the framework of the mode coupling theory of the dynamic glass transition. the presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution ...

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...

Here, we present our work on preparing a novel nanomaterial composed of inorganic binding peptides and magnetic nanoparticles for inorganic mining. Two previously selected and well-characterized gold-binding peptides from cell surface display, AuBP1 and AuBP2, were exploited. This nanomaterial (AuBP-MNP) was designed to fulfill the following two significant functions: the surface conjugated gol...

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...
