The Use of Nanoscale Zero Valent Iron for Environmental Remediation – Benefits and Possible Pitfalls

, , , , , , , ,
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 [...]

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

, , , , , , , , , , ,
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 [...]

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

, , , , , , ,
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

, , , , , , , , , ,
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, [...]

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 [...]
