Aggregation and Toxicology of Titanium Dioxide Nanoparticles
In their study of inhalation exposure of titanium dioxide particles, Grassian et al. (2007) presented a transmission electron micrograph (TEM) (their Figure 2A) as an image of “dispersed” TiO2 nanoparticles. Yet, the TiO2 nanoparticles in this TEM do not appear to be dispersed. There is clear evidence of self-organization of the nanoparticles into distinct assemblages, separated by relatively l...
متن کاملSynthesis of titanium dioxide nanoparticles using Echinacea purpurea herba
Nowadays green synthesis of metal nanoparticles is a developing area of research. In this study, titanium dioxide nanoparticles were biosynthesized using an aqueous solution of Echinacea purpurea herba extract as a bioreductant. This is novel and interesting method for synthesis of TiO2 nanoparticles. The prepared titanium dioxide nanoparticles were characterized using ultraviolet–visible spect...

متن کاملInhalation Exposure Study of Titanium Dioxide Nanoparticles with a Primary Particle Size of 2 to 5 nm
BACKGROUND Nanotechnology offers great promise in many industrial applications. However, little is known about the health effects of manufactured nanoparticles, the building blocks of nanomaterials. OBJECTIVES Titanium dioxide (TiO(2)) nanoparticles with a primary size of 2-5 nm have not been studied previously in inhalation exposure models and represent some of the smallest manufactured nano...
متن کاملEffect of Methanol and Titanium Dioxide Nanoparticles on Phytochemical Properties of Artichoke (Cynara scolymus L.)
Extended Abstract Introduction and Objective: In recent years, studies have focused on the use of new compounds that can be synthesized inside the plant and increase the photosynthetic efficiency of the plant. Some of these compounds include micronutrients and alcohols. Alcohols such as methanol as a carbon source will increase photosynthetic efficiency and improve plant growth parameters. Tit...
