today, there is an increasing interest in the use of metal nanoparticles in health sciences. amongst all nanoparticles, the gold nanoparticles have been known to kill the cancer cells under hyperthermic condition by near-infrared frequency electromagnetic waves. on the other hand, although there are different physiochemical methods for disinfection of microbial pollution, however applications o...

SNP Genotyping In article number 2105538, Jungkyu Choi, Hyojin Lee, Nakwon an co-workers present SWITCH for multiplex single nucleotide polymorphism genotyping. Invaders (single-stranded oligonucleotides, colored in blue and yellow) obtained from a gold nanoparticle induce fluorescence recovery specific regions of shape-coded hydrogel microparticle.

The present work demonstrated a green approach of synthesis of gold nanoparticles using Eupatorium odoratum leaf extract as reducing and stabilizing agent assisted with microwave irradiation. Effects of various concentrations of leaf extract on the preparation of gold nanoparticles have been investigated and it was monitored by undertaking UV-vis spectroscopic studies. The experimental results ...

The direct reagentless electrochemical detection of recombinant firefly luciferase binding with gold electrode modified with nickel ions has been carried out. Self-assembly of molecules of functional disulfide containing chelating moieties on the gold electrode was monitored by contact angle measurements and confirmed by electrochemical data as three times decrease of electric double layer capa...

This study involved preliminary laboratory test work to identify the relative leaching response to cyanidation and thiourea leaching of an oxidized low grade gold ore based on characterization studies. Huge reserves of gold deposits have been reported from different parts of Iran, especially at Neishaboor area with gold grade of approx 4 ppm. For the mineralogical composition, the nature of the...

hired is a large gold prospecting area which is located in south khorasan province, in the east of iran. gold mineralization is found in 4 target areas covering about 24 km2. the host rocks are mainly tertiary volcanics, some jurassic and cretaceous sediments. sub-volcanic rocks are of magnetite series (gabbros to diorite) and ilmenite series (granite-granodiorite-monzonite) which have intruded...
