Engineered nanoparticles (ENP) are increasingly being integrated into polymeric infrastructure and food packaging materials worldwide. ENPs can improve product strength, extend infrastructure service life, and increase a polymer’s antimicrobial resistance and oxygen barrier properties. While [...]
The growing use of nanomaterials in commercial goods and as novel carriers for drug delivery is generating increasing questions about possible risks for human health and environment, due to the lack of an in-depth assessment [...]
We report the effect of carbon nanotubes at the cellular level using purified single-walled carbon nanotubes (SWNTs) resuspended in physiological compatible phosphate buffered saline (PBS) and systematically study its impact on Chinese Hamster Ovarian (CHO) [...]
We show that the dynamics of proteins-NP interactions are differently mediated by different cellular media, which are the liquid environments where NPs encounter cells. We used, as a model, spherical NPs (citrate-capped gold nanoparticles, AuNPs) [...]
The combination of high toxicity and widespread occurrence has created a pressing need for effective monitoring of arsenic in groundwater. Although laboratory analysis has been used to measure arsenic in collected groundwater samples, the time [...]
How do we balance the potential hazards from new and inadequately characterized engineered nanomaterials with the potential and power of nanotechnology? It has become apparent, that potential environmental health effects are critical factors in the [...]
The California Environmental Protection Agency’s Department of Toxic Substances Control (DTSC) initiated the second chemical information call-in on nanometal oxides (titanium dioxide, cerium oxide, and zinc oxide), nanometals (silver and zero valent iron), and quantum [...]
The health impact of exposure to TiO2 nanoparticles is poorly documented although exposure to the particles is known to elicit inflammatory responses in lung tissue. We recently found treatment with TiO2 micro- or nanoparticles induce [...]

Assessment of toxicity of 10 nm, 50 nm and 1 um Fe3O4 particles based on shift in the cell population of the broncho-alveolar lavage fluid after their intratracheal instillation into lungs of rats and on [...]
Cell model systems in vitro facilitate the high through-put screening of putative toxicity of a variety of nanomaterials, including nanoparticles. However, most of such cell models consisted of non-neural cells. We have developed several central [...]
The molecular mechanisms underlying the pathophysiology of peripheral neuropathies have not been fully elucidated. To meet the need for suitable cell culture models in vitro of peripheral nervous system (PNS) neural cells that allow long-term [...]
A sensor that integrates the detection and transduction of the signal to a display is presented in this work. The device comprises a holographic grating embed in a polymer. The polymer is an elastomer that [...]
The research proposes an electrochemical mechanism of AC-corrosion in CP condition. Electrochemical tests were carried out on carbon steel in simulated soil conditions to identify AC corrosion risk related parameters during cathodic polarization, like AC [...]

At the present, we are focused on Korean consumer products because in our recent IP landscaping study, we have found that for all major patenting countries, Korea leads in nanosilver applications, with more than 1500 [...]
Nanotechnology companies are facing increasing scrutiny as federal and state agencies adopt regulations and propose recommended workplace practices and exposure standards. In addition, more studies are being released that indicate that some nanomaterials present the [...]
