Nanosized titanium dioxide (nano-TiO2) particles are used in diverse products and devices, including photocatalytic water splitting and solar cells whose successful commercialization is still facing scientific and technologi-
The EU Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) demands the implementation of alternative methods for analyzing the hazardous effects of chemicals including particulate formulations. In the field of inhalation toxicology, a variety of in vitro models have been developed for such studies. To simulate the in vivo situation, an adequate exposure de...
Mike Meier University of California, Davis September 13, 2004 Figure 1. FEG-SEM image of nanosized aluminum oxide powder. Note the magnification and the size of the micron bar. Also note how the smaller particles and the edges of the larger particles appear to be somewhat transparent. This is because much of the 5 kV electron beam can pass through these thinner parts of the particles. CRYSTALLI...
The internal distribution behavior of micro/nanosized ceramics and metal particles administered into the tail vein of mice was determined using magnetic resonance imaging, scanning X-ray analytical microscopy and inductively coupled plasma-atomic emission spectroscopy. After administration through the tail vein of mice, the particles circulated by blood flow reached and then remained temporaril...
Nanosized maghemite particles were synthesized, precoated (with dimercaptosuccinic acid) and surface-functionalized with anticarcinoembryonic antigen (anti-CEA) and successfully used to target cell lines expressing the CEA, characteristic of colorectal cancer (CRC) cells. The as-developed nanosized material device, consisting of surface decorated maghemite nanoparticles suspended as a biocompat...
The existence of nanosized particles at the workplace is not a new phenomenon . As early as in 1997, the Deutsche Forschungsgemeinschaft, Commission for the investigation of Health Hazards of chemical compounds in the work area, defined the term “ultrafine particles” in its List of Maximale ArbeitsplatzKonzentration (MAK) and Biologischer Arbeitsstoff-Toleranzwert (BAT) Values . The definition ...
BACKGROUND Both thermotherapy and arsenic have been shown to be active against a broad spectrum of cancers. To reduce the limitations of conventional thermotherapy, improve therapeutic anticancer activity, reduce the toxicity of arsenic on normal tissue, and increase tissue-specific delivery, we prepared a nanosized As2O3/Fe3O4 complex (Fe3O4 magnetic nanoparticles encapsulated in As2O3). We as...
