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 [...]

Impacts of Three nC60 Dispersal Methods on E. coli Growth

Dai J., Chen G.H., HKUST, CN

The preparations of nC60 through water directly and toluene or THF indirectly represent all possible dispersal routes of fullerene particles in aquatic ennvironemnts. These different dispersal routes may result in different toxicity on microorganisms such [...]

Phagocytizing cells recruitment and activity in response to pulmonary deposition of magnetite particles of different size in nanometer and micrometer ranges

Privalova L.I., Katsnelson B.A., Kuzmin S.V., Degtyareva T.D., Sutunkova M.P., Yeremenko O.S., Khodos M.Y., Kositsina A.N., Malakhova N.A., Glazyrina J.A., Medical Research Center for Prophylaxis and Health Protection in Industrial Workers, RU

It is often maintained that nanoparticles are poorly recognized by host’s defence mechanisms and, specifically, cause weak attraction of phagocytes and are therefore removed from lungs ineffectively. However, intratracheal instillation of water-suspended magnetite nanoparticles caused [...]

The Effect of Nanoparticles on Bacteriophage Infection

Nickel A.L., Pedulla M.L., Kasinath R.K., Montana Tech, US

We present the results of our recent findings that the introduction of apatite nanoparticles (~10 nm) in a classical phage-bacteria infection scenario increases the efficacy of the phage infection as investigated through plaque formation. The [...]

Behaviour of Aerosol Nanoparticles Released into Simulated Workplace Environment

Wu Q., Marion S., Seipenbusch M., Kasper G., DNV, NO

In this work we report results from our EU research project NANOTRANSPORT. This project addressed the occupational health risks associated with aerosols released during manufacture of nanoparticles. The main objective of this project was to [...]

Applying Basic Risk Management Principles to Nanomaterial Processes

Geraci C.L., National Institute for Occupational Safety and Health, US

Health, safety, and environmental issues continue to be a high priority area to be addressed during the commercialization of nanomaterials or nanomaterial-enabled products. Facilities engaged in the production or use of engineered nanomaterials, specifically nanoparticles, [...]

Lessons learned from the field, how to protect yourself from occupational exposure to engineered nanomaterials

Hodson L.L., Geraci. M. Methner C.L., Crawford C., CDC/NIOSH, US

NIOSH has visited over 26 nanomaterial facilites, evaluated workplace exposures and created recommended guidance to reduce potential exposures to nanomaterials. A summary of lessons learned about effective control strategies will be shared.
