Functional polymer hydrogels for water purification applications
Filtration is necessary in many engineering field. Polymeric membranes have been used in filtration application for more than a decade. However, some of the contaminants, e.g. radiounuclides and toxic metals, present in soluble form in [...]
The Use of Nanoscale Zero Valent Iron for Environmental Remediation – Benefits and Possible Pitfalls
Chan-Remillard S., Borda M., Crawford A., Kloschinsky T., Stenroos P., Marques L., Goudey J.S., HydroQual Ltd and Golder Associates Ltd/Inc., CA
Nanoscale zero valent iron (nZVI) is the primary nanoscale particle that is being used for environmental remediation of contaminated groundwater and soils. Golder Associates Ltd. and HydroQual Laboratories (a wholly owned subsidiary of Golder) has [...]
A Non-contact Co-Culture Model of Peripheral Neural Cells for Nanotoxicity, Tissue Engineering and Pathophysiological Studies
Cell culture models in vitro have long served as tools for the elucidation of pathophysioligcal cellular and molecular mechanisms of diseases. Recently these versatile model systems have permeated into toxicology and tissue engineering research. Although [...]
Modeling Aggregation and Size Distribution of Nanoparticles with Monte Carlo Simulation
The size distribution of the nanoparticles and their aggregates is crucial for predictions of the fate and transport of nanoparticles in the environment. A computational model was developed in the present work based on a [...]
Lessons learned from the field, how to protect yourself from occupational exposure to engineered nanomaterials
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.
Applying Basic Risk Management Principles to Nanomaterial Processes
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, [...]
The Effect of Nanoparticles on Bacteriophage Infection
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 [...]
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 [...]
Comparing Cytotoxicity of ZnO Nanoparticles in Exposure to Serum/Serum-free Cell Culture Medium
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 [...]
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 [...]
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, [...]
Cell damage by energy saving light bulbs
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) [...]
The Mechanism of Mediated Electrochemical Dissolution of Semiconducting Metal Oxide Particle
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 [...]
California’s Efforts to Safe and Responsible Nanotechnologies: Information Call-in from Manufacturers of Nanometals and Oxides
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 [...]
Potential Insurance Coverage Issues Arising from Nanotechnology: Big Risks Could Come in Small Packages
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 [...]
Cytotoxicity Assessment of Human Lung Alveolar Cell Exposed to Nanoparticles and Polycyclic Aromatic Hydrocarbons Exhausted from Motorcycle
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 [...]
