The aim of the present study was to explore the preparation of arsenic trioxide (As2O3) nanoparticles and examine the antitumor effects of these nanoparticles on NB4 cells. As2O3 nanoparticles were prepared using the sol-gel method and characterized using transmission electron microscopy and energy dispersive spectroscopy. The results indicated that the As2O3 nanoparticles prepared in the prese...

The mass concentrations of airborne particles in the atmospheric, indoor, and industrial environments are regulated by air quality standards. Epidemiological studies show that there are significant positive correlations between particle mass concentrations and adverse health effects. In this context nanoparticles in the air, which are defined as particles with a diameter (Dp) of less than 50 nm...

Increasing the citrate concentration during the seeded growth synthesis of gold nanoparticles yields materials with decreased aspect ratios and increased defect densities. The stability of these nanoparticles is attributed to variations in their overall Gibb's free energy.

We highlight a novel fluorescence analysis for sensitive and selective detection of EV-71 and CV-A16 by combining labelling technology based on dual-colour upconversion fluorescence nanoparticles (UCNPs) with magnetic bioseparation and concentration technology based on magnetite nanoparticles (MNPs).

An in vitro study was conducted to know the veridical properties of silver nanoparticles synthesized from   locally available white button mushrooms (Agaricus bisporus). The characterized colloidal silver nanoparticles exhibited as an excellent virucidal property on viral strain Bacteriophage. The viral inactivation process was increased with increasing the concentration of colloidal s...

the nanomaterials have important application in different field of science such as biology and pharmacology, which draws the attention of biologists towards this field of study more than before. as the worldwide mortality rate is high due to the pathogens and especially because of the bacteria associated aeromonas and the antibacterial effect of metal nanoparticles is well known for centuries, ...

in this study, iron oxide nanoparticles (maghemite) were used to remove ni (ii) and cr (vi) from mine’s waste water. first, by using novel single step, maghemite nanoparticles (?-fe2o3) produced at room temperature, without the use of natural solvents and oxides. the average particle size of the maghemite was estimated to be 14 nm, by transition electron microscope (tem(. various factors influe...
