Gold nanoparticles have been available for many years as a research tool in the life sciences due to their electron density and optical properties. New applications are continually being developed, particularly in nanomedicine. One drawback is the need for an easy, real-time quantitation method for gold nanoparticles so that the effects observed in in vitro cell toxicity assays and cell uptake ...

Abstract Radioactive iodine (e.g. I-125, I-131) have been used for decades in the medical community cancer treatment and imaging. Using gold nanoparticles as a carrier opens possibilities of new treatments also tracking cancerous cells. To design an optimized version nanoparticle such purpose, we need to understand bonding mechanism gauge strength bonding. this end performed theoretical calcula...

objective(s):   gold nanoparticles (gnps) command a great deal of attention for biomedical applications nowadays. the data about the degree of toxicity and the accumulation of gold nanoparticles in-vivo is not enough to judge.  materials and methods:  a total of 32 healthy male wistar rats were randomly divided into 4 including: three gnp-treated and one control group. groups 1, 2 and 3 receive...

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 ...

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 ...

Targeted radiotherapies maximize cytotoxicty to cancer cells. In vivo α-generator targeted radiotherapies can deliver multiple α particles to a receptor site dramatically amplifying the radiation dose delivered to the target. The major challenge with α-generator radiotherapies is that traditional chelating moieties are unable to sequester the radioactive daughters in the bioconjugate which is c...
