As the number of commercial and consumer products containing engineered nanomaterials (ENMs) continually rises, the increased use and production of these ENMs presents an important toxicological concern. Although ENMs offer a number of advantages over traditional materials, their extremely small size and associated characteristics may also greatly enhance their toxic potentials. ENM exposure ca...

Nanoparticles appear to induce toxic effects through a variety of mechanisms including generation of reactive oxygen species (ROS), physical contact with the cell membrane and indirect catalysis due to remnants from manufacture. The development and subsequent increasing usage of nanomaterials has highlighted a growing need to characterize and assess the toxicity of nanoparticles, particularly t...

Nanotechnology is a promising tool for the development of innovative treatment strategies allowing to overcome obstacles encountered by classical drug delivery. This has led to the development of nanomedicine. Indeed, nano-delivery systems (NDS) may allow the controlled release of therapeutics, protection of drugs against degradation, targeted drug delivery and facilitated transport across barr...

The advent of engineered nanoparticles (ENPs) and their increased use has remarkably improved the performance of basic materials and consumer products, but has also increased the potential for ENP release into the environment. Technical procedures, more accurate and specific than those for routine chemical analysis, are needed for characterization and quantification of ENPs at environmentally r...

Extensive use of nanotechnology in multiple commodities is raising concerns about nanotoxicity. In particular, many studies have reported the health-hazardous effects titanium dioxide nanoparticles (TiO2-NPs). The present study focuses on toxicity and accumulation TiO2-NPs tilapia (Oreochromis mossambicus). For this purpose, was kept water tanks, acclimatized for 14 days, treated with different...

Objective (s): Titanium dioxide nanoparticles (TiO2 NPs) have been recognized as biologically inert material and have been used in a multitude of applications. Nevertheless, the negative impact on the human health is not yet well understood. Aim of the work: The study attempted to evaluate the epigenetic changes of the genome, in the form of DNA methylation in liver tissue samples, resulting fr...

Extensive research on the nutritional and medical application of selenium nanoparticles (SeNPs) was performed in past decades. Besides nutritional values, new characteristics such as antibacterial and anticancer properties depict a bright future for high Selenium (Se) consumption in the coming years. Se is essential for the proper functioning of most of the m...

COVID-19 is a highly infectious respiratory disease that resulted in global pandemic has affected every stage and sector of life. Although it mainly seen as health issue, its impacts ripple effects also resonated the education, technology, agriculture, research fields, creating socio-economic disruptions across globe. In bid to curb wide spread disease, diverse sudden restriction measures were ...
