We evaluated recently published articles relevant to the biological effects of titanium dioxide (TiO2) particles on local endogenous cells required for normal bone homeostasis, repair, and implant osseointegration. Structural characteristics, size, stability, and agglomeration of TiO2 particles alter the viability and behavior of multiple bone-related cell types. Resulting shifts in bone homeos...

Anatase titanium dioxide nanoparticles (TiO2-NPs) were synthesized by sol-gel method using rice straw as a soft biotemplate. Rice straw, as a lignocellulosic waste material, is a biomass feedstock which is globally produced in high rate and could be utilized in an innovative approach to manufacture a value-added product. Rice straw as a reliable biotemplate has been used in the sol-gel method t...

Nanoparticles synthesised by fungi have various applications and is much effective than the nanoparticles synthesised by other means. The present study is aimed to determine the antimicrobial potential of Titanium dioxide nanoparticles synthesised from the fungus, Aspergillus niger. The synthesised nanoparticles were characterised using UV spectrophotometer, SEM, and XRD. The antibacterial acti...

titanium dioxide is one kind of important materials, which has been extensively investigated because of its unique electronic and optical properties. a large number of efforts have been made to synthesize tio2 materials with different methods. in this review paper, we summarize the synthesis pathways, morphology, as well as crystallization of the nanostructured tio2. in addition, we also mentio...

Tubular heterostructures based on titanium dioxide (TiO2) and silica nanotubes (SNTs) with high photocatalytic activity have been successfully obtained by a simple combination of an electrospinning technique and a solvothermal process. The as-prepared products were characterized by field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (X...

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...

Titanium is a very important element for several industrial applications, being one of the ninth most abundant elements in the Earth’s crust (0.63% wt). In this work it will discuss the different mining and industrial activities involved in the production of titanium dioxide. The first step analyzed will treat about the beneficiation mining process of titanium mineral, and secondly, it will dis...
