Analysis of Membrane Filtration Efficiency in Removal of Metal Oxide Nanoparticles from Aqueous Nanoparticle Suspension in the Presence of Coagulation Pretreatment

Surawanvijit S., Kim M., Cohen Y., University of California, Los Angeles, US

The introduction of nanoparticles (NPs) into aqueous environment is expected to rise with increased manufacturing and use of nanoparticles. There is a need to identify efficient and methods for NP removal and such methods must [...]

Cytotoxicity Assessment of Human Lung Alveolar Cell Exposed to Nanoparticles and Polycyclic Aromatic Hydrocarbons Exhausted from Motorcycle

Chien S.M., Huang Y-J, Chuang C.C.Y., Hsiao I.L., Kuo Y.F., National Tsing Hua University, TW

The potential harmfulness of traffic pollutants, particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs), were elevated with the increment of motocycles. However, the toxicology of the nanoparticulate and particle-PAHs (p-PAHs) has rarely been evaluated in [...]

Potential Insurance Coverage Issues Arising from Nanotechnology: Big Risks Could Come in Small Packages

Fink A.J., Howrey LLP, US

Businesses involved with nanotechnology should undertake risk management that assesses the potential losses that could arise as a result of nanotechnology and develop a broad insurance coverage program that takes these risks into account. Some [...]

California’s Efforts to Safe and Responsible Nanotechnologies: Information Call-in from Manufacturers of Nanometals and Oxides

Kang H.Y., California Environmental Protection Agency, US

The nanotechnologies and their applications encompass many areas. However, because of their unique properties, nanomaterials might have the potential to adversely effects to human health and the environment. The potential risks of nanomaterials such as [...]

The Mechanism of Mediated Electrochemical Dissolution of Semiconducting Metal Oxide Particle

Inoue A., Japan Atomic Energy Agency,Tokai, JP

The dissolution of plutonium dioxide (PuO2) is of a fundamental importance from the point of view of energy as well as environment. In this work the mechanism of the mediated electrochemical dissolution of semiconducting plutonium [...]

Cell damage by energy saving light bulbs

Mironava T., Rafailovich M.H., SUNY at Stony Brook, US

The growing concern regarding green house gas emissions during power generation has increased awareness regarding energy conservation. Next to transportation, lighting is one of the major sources of energy consumption. Compact fluoresce light bulbs (CFL) [...]

Novel Mycotoxin Collection System using Magnetic Nanoparticles for Determination of Aflatoxin B1 and Zearalenone in Feed

Cha S-H, Lee J-K, Jung H-S, Kim H.-J., Kim S-H, Kim H.-J., Kim S-H, Choi C-U, Kang H-G, National Veternary Research and Quarantine Service, KR

Introduction: A common method for determination of mycotoxins contaminated in feeds combines immunoaffinity chromatography (IAC) and high-performance liquid chromatography (HPLC) with UV detection1,2. However, the IAC method to collect mycotoxins is expensive and time-consuming. Moreover, [...]

Effect of Dynamic Environment on the Interaction between Nanoparticles and A549 Monolayer

Patel H., Kim H., Kwon S., Utah State University, US

The carbon nanotube (CNT) has been well explored for many proven applications, but very little explored to understand its potential toxic effects. It is crucial to develop viable alternatives to in vivo tests to evaluate [...]

Elucidation of Neuroprotective Properties of Astrocytoma (Astrocytes-like) Cells in Neural Cell Culture Models In Vitro: Applications in Tissue Engineering and Nanotoxicology

Wong Y.Y.W., Jaiswal A., Dukhande V.V., Bhushan A., Leung S.W., Lai J.C.K., Idaho State University, US

Evidence is accumulating that cell culture models in vitro facilitate high throughput and mechanistic studies in tissue engineering. We have developed several cell models for the systematic investigation of molecular mechanisms underlying the putative cytotoxicity [...]

Comparing Cytotoxicity of ZnO Nanoparticles in Exposure to Serum/Serum-free Cell Culture Medium

Hsiao I.L., Huang Y-J, National Tsing Hua University, TW

The aim of this study is to evaluate the influence of serum in cell culture medium on nanotoxicity to human lung epithelial cells (A549). We found nano-ZnO had greater toxicity as it was suspended by [...]
