use of nano-materials has increased in various aspects of human life. however, possible outbreak of nano-materials toxicity in humans and other organisms is one of the future challenges. different chemical precursors which are used in chemical approaches for production of nano-materials may have secondary and sometimes toxic effects in living organisms. these secondary effects may be reduced in...

A potentially useful means of predicting the pulmonary risk posed by new forms of nano-structured titanium dioxide (nano-TiO2) is to use the associations between the physicochemical properties and pulmonary toxicity of characterized forms of TiO2. In the present study, we conducted intratracheal administration studies in rats to clarify the associations between the physicochemical characteristi...

BACKGROUND The release of heavy metal-containing nanoparticles (NP) into the environment may be harmful to the efficacy of beneficial microbes that function in element cycling, pollutant degradation and plant growth. Nanoparticles of Ag, CuO and ZnO are of interest as antimicrobials against pathogenic bacteria. We demonstrate here their antimicrobial activity against the beneficial soil microbe...

The water-soluble, hydroxylated fullerene [fullerol, nano-C60(OH)22-26] has several clinical applications including use as a drug carrier to bypass the blood ocular barriers. We have assessed fullerol's potential ocular toxicity by measuring its cytotoxicity and phototoxicity induced by UVA and visible light in vitro with human lens epithelial cells (HLE B-3). Accumulation of nano-C60(OH)22-26 ...

Neodymium is a future-oriented material due to its unique properties, and its use is increasing in various industrial fields worldwide. However, the toxicity caused by repeated exposure to this metal has not been studied in detail thus far. The present study was carried out to investigate the potential inhalation toxicity of nano-sized neodymium oxide (Nd2O3) following a 28-day repeated inhalat...

Conventional therapies of cancer cause serious side effects, systemic toxicity, poor quality of life of patients, accompanied with tumor resistance and recurrence which discourage their long term use. Therefore, highly precise anticancer therapies with minimal side effects are needed to be identified. Curcumin’s widespread availability, safety, low cost and anticancer activity justify its devel...

Now safety concern of in vivo nano-carriers toxicity is apparently hindering the extensive applications of nanotechnology in medical sciences. Many studies on the effects of nanomaterials in vitro and in vivo have been published, and revealed that nanomaterials including carbon nanotubes, fullerenes, quantum dots (for example CdS) and oxide nanoparticles (NPs) (for example ZnO, CuO and TiO2) ex...

objective(s): binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. materials and methods: template free zsm-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/zsm-5 hybrid composites with nano chitosan...

Abstract Nanoemulsion of S. pepper could control cabbage pests but optimization is needed for the composition because low toxicity. The purpose this research was to optimized nanoemulsion using citronella waste that increases stability and reduces size particle. insecticidal activity tested leaves residual method. experimental design used a completely Randomized Design (CRD) which consisted fiv...
