Digital detection of exosomes by interferometric imaging [PDF]

open access: yes, 2016
Exosomes, which are membranous nanovesicles, are actively released by cells and have been attributed to roles in cell-cell communication, cancer metastasis, and early disease diagnostics.

A new strategy to destroy cancer cells using osmium dioxide (OsO2) and osmium tetroxide (OsO4) nanoparticles and magnetic fields under synchrotron and synchrocyclotron radiations

open access: yesInternational Journal of Advanced Chemistry, 2021
In the current research, a new strategy to destroy cancer cells using Osmium Dioxide (OsO2) and Osmium Tetroxide (OsO4) nanoparticles and magnetic fields under synchrotron and synchrocyclotron radiations is investigated. The calculation of thickness and optical constants of Osmium Dioxide (OsO2) and Osmium Tetroxide (OsO4) a new strategy to destroy ...

Dicarba-closo-dodecarborane-containing half-sandwich complexes of ruthenium, osmium, rhodium and iridium : biological relevance and synthetic strategies [PDF]

open access: yes, 2012
This review describes how the incorporation of dicarba-closo-dodecarboranes into half-sandwich complexes of ruthenium, osmium, rhodium and iridium might lead to the development of a new class of compounds with applications in medicine. Such a combination

Carbon monoxide adsorption on platinum-osmium and platinum-ruthenium-osmium mixed nanoparticles

open access: yesThe Journal of Chemical Physics, 2013
Density functional calculations (DFT) on carbon monoxide (CO) adsorbed on platinum, platinum-osmium, and platinum-ruthenium-osmium nanoclusters are used to elucidate changes on the adsorbate internal bond and the carbon-metal bond, as platinum is alloyed with osmium and ruthenium atoms.

Yeast-derived biosynthesis of silver/silver chloride nanoparticles and their antiproliferative activity against bacteria [PDF]

open access: yes, 2016
Here, we provide the first evidence of yeast strains assisted Ag/AgCl-NPs production in vitro. The formed nanoparticles were characterized by spectroscopic and electron microscopy approaches. UV-vis supported the biosynthesis. TEM analysis evidenced that

Mechanism of cellular uptake of genotoxic silica nanoparticles. [PDF]

open access: yes, 2012
Mechanisms for cellular uptake of nanoparticles have important implications for nanoparticulate drug delivery and toxicity. We have explored the mechanism of uptake of amorphous silica nanoparticles of 14 nm diameter, which agglomerate in culture medium ...

Monte Carlo Calculation of linear attenuation coefficients and photon scattering properties of novel concretes loaded with Osmium, Iridium and Barite nanoparticles [PDF]

open access: yesPolish Journal of Medical Physics and Engineering, 2021
Abstract Introduction: Recent studies have shown that the use of high-density nanoparticles (NPs) in concrete composition improves its radiation shielding properties. In the present study, the linear attenuation coefficients and photon scattering properties of newly developed high-density Nano-concretes have been ...

Xylem surfactants introduce a new element to the cohesion-tension theory [PDF]

open access: yes, 2016
Vascular plants transport water under negative pressure without constantly creating gas bubbles that would disable their hydraulic systems. Attempts to replicate this feat in artificial systems almost invariably result in bubble formation, except under ...

Uptake and cytotoxicity of citrate-coated gold nanospheres : comparative studies on human endothelial and epithelial cells [PDF]

open access: yes, 2012
The use of gold nanoparticles (AuNPs) for diagnostic applications and for drug and gene-delivery is currently under intensive investigation. For such applications, biocompatibility and the absence of cytotoxicity of AuNPs is essential. Although generally

Use of Desulfovibrio and Escherichia coli Pd-nanocatalysts in reduction of Cr(VI) and hydrogenolytic dehalogenation of polychlorinated biphenyls and used transformer oil [PDF]

open access: yes, 2012
BACKGROUND Desulfovibrio spp. biofabricate metallic nanoparticles (e.g. ‘Bio-Pd’) which catalyse the reduction of Cr(VI) to Cr(III) and dehalogenate polychlorinated biphenyls (PCBs). Desulfovibrio spp.
