“…For instance, a study conducted a few years ago found that exposure of BEAS‐2B cells to TiO 2 NPs induced apoptosis and oxidative stress . Another study investigated the effect of TiO 2 NPs on human astrocyte and neuronal cells after acute and long‐term exposure . Both acute and prolonged exposure even at low dose seem to affect the proliferative capacity of the cells.…”

Synthetic nanomaterials have many unique chemical and physical properties, mainly due to their high specific surface area and quantum confinement effect. Specifically, titanium dioxide (TiO ) nanomaterial has high stability, anticorrosive, and photocatalytic properties. However, there are concerns over adverse biological effects resulting from bioeffects. This study was to investigate adverse effects associated with acute ingestion of TiO nanofiber (TDNF). TDNF was fabricated via electrospinning method, followed by dissolution in water. Six- to seven-week-old male Sprague Dawley rats were exposed to a total of 0, 40, and 60 ppm of TDNF for 2 weeks via oral gavage. Serum total protein and weight gain during the course of this study displayed marginal concentration-dependent alterations. These findings were followed by a global gene expression analysis to identify which transcripts might be responsive to TNDF toxicity. Differentially expressed mRNA levels were dose-dependently higher in animals exposed to TNDF. The majority of the affected genes were biochemically involved in immune response and inflammation. We believe this is due to the fact that TNDF is unable to penetrate the cell and forms phagocytosis sites that trigger inflammatory and immune response. All results taken together, short-term ingestion of TNDF produced marginal effects indicative of inflammation. Finally, the broad gene expression data were validated through quantification of immunoglobulin heavy chain alpha (Igha). Igha gene was upregulated in treated groups, showing similar expression patterns to the global gene expression data.

“…Their sizedependent MRI properties together with their superparamagnetic behavior, biocompatibility and chemical stability place them as a particularly important NP type for biomedical applications [83]. IONPs are typically composed of magnetite (Fe3O4) and/or maghemite (γ-Fe2O3) nanocrystals, which may exhibit different shapes (spheres, cubes, rods, rings, flowers, pyramids, etc.).…”

Abstract:The combination of radioisotopes and nanomaterials is creating a new library of tracers for molecular imaging, exploiting the sensitivity of nuclear imaging techniques and the size-dependent properties of nanomaterials. This new approach is expanding the range of applications, including the possibility of theranostics. Among the many different combinations, the use of 68 Ga as the radioisotope in the radio-nanomaterial is particularly convenient. The physicochemical properties of this isotope allow incorporating it into many materials with great chemical flexibility. Furthermore, its production from a benchtop generator eases the preparation of the tracer. Here, we review main results from the last years in which a nanomaterial has been radiolabeled with 68 Ga. In thus process, we pay attention to the use of nanomaterials for biomedical imaging in general and main properties of this radioisotope. We study the main methods to carry out such radiolabeling and the most important applications for molecular imaging.

Magnetite (Fe 3 O 4 nanoparticles were synthesized using FeCl 3 , FeSO 4 (initial molar ratio Fe 2+ /Fe 3+ is fixed at 1/1) and KOH as raw materials by the hydrothermal method. The crystallographic and microstructures, thermal and magnetic properties of Fe 3 O 4 were characterized by X-ray powder diffraction, scanning electron microscopy, thermogravimetric analyses and vibrating sample magnetometer. The results show that by controlling the reaction temperature and time, Fe 3 O 4 nanocrystals with homogeneous morphology and nanometer grain sizes can be obtained. The Fe 3 O 4 nanocrystals are stable up to temperature of 115 C in air then undergo allotropic transformation to maghetite and hematite. The kinetics of the grain growth of Fe 3 O 4 nanocrystals during the hydrothermal process were investigated. Based on the experimental data, the radius of the initial Fe 3 O 4 particles in the hydrothermal synthesis was found to be 23 nm. The average particle radius increases linearly with the reaction time in agreement with the Lifshitz-Slyozov-Wagner model for coarsening and the rate constant for the coarsening increases with the temperature of the hydrothermal reaction.
