Dr Peter Wick (EMPA, Swiss Laboratories for Materials Testing and Research, Switzerland)23/03/2009, 10:15Nanoparticulate materials and among them, carbon nanotubes (CNTs) are a new type of materials that generate high expectations due to their unique physical, chemical and optical properties. Due to the predictably increasing production of various types of carbon nanotubes and other nanoparticle-containing products, it can be expected that environmental and public exposure to...Go to contribution page

Dr Jayne Wallace (University of Oxford, UK)23/03/2009, 11:00There is great interest in exploiting the novel properties of carbon nanotubes (CNTs) for use in biology and medicine. For example, CNTs have potential application in drug delivery, cancer and gene therapy, and as components of biosensors. However, prior to their usage we need to both develop methods to overcome the hydrophobicity-induced aggregation of CNTs, and also to understand the...Go to contribution page

Dr Anne Thoustrup Saber (National Research Centre for the Working Environment, Copenhagen, Denmark)23/03/2009, 13:15Different kinds of particles have been shown to induce genotoxic damage after deposition in the lung. This may result in cancer if the DNA damage is not repaired or if selective apoptosis of the damaged cells fails. A primary mechanism of particle-induced genotoxicity has been attributed to the surface characteristics. A decade ago a secondary pathway for genotoxicity was proposed on...Go to contribution page

Dr Anna Shvedova (West Virginia University, USA)23/03/2009, 14:30Advancements in nanotechnology and broad applications of nanomaterials raise the issue of their potential adverse health effects particularly in occupational and environmental settings. Among different nanomaterials, Single-Walled Carbon Nanotubes (SWCNT) – with their unique physico-chemical, electronic and mechanical properties – are emerging as important objects of toxicological...Go to contribution page

Dr Pekka Koskinen (University of Jyväskylä, Finland)23/03/2009, 15:15Nanoscale imaging techniques can be accurate, but sometimes things are not as they seem. I will present two cases where the imaging technique itself causes the measured phenomenon. First case relates to TEM imaging of a metal atom diffusing in graphene, and the second relates to STM imaging of small potassium islands on graphite. In both cases theory is needed to interpret the...Go to contribution page

Prof. Yuri Volkov (Trinity College Dublin, Ireland)24/03/2009, 09:15Rapid development of nanotechnology consistently increases the likelihood of human contact with environmentally presented and manufactured nanomaterials, i.e. the tiny objects ranging in size from one to several hundreds of nanometres and featuring an extreme diversity in shapes and physico-chemical properties. However, there is still very little definitive systematic information about...Go to contribution page

Dr Luca Monticelli (INSERM Paris, France)24/03/2009, 10:00Carbon nanoparticles are biologically active and can enter easily different kinds of cells. It is not clear how these materials enter cell membranes and what are the mechanisms of cell damage. Recently it has been found that natural organic matter (NOM) interacts strongly with fullerene and carbon nanotubes, altering their interaction with cells. Gallic acid is one of the main components...Go to contribution page

Prof. Peter Tieleman (University of Calgary, Canada)24/03/2009, 11:15The thermodynamics of interactions between the lipid bilayer and other molecules determines to a large extend the transport rate of these molecules across the bilayer as well as the nature of the process involved in partitioning. In the past few years we have studied these interactions for a range of organic molecules, for lipids, cholesterol, fullerenes, and models of carbon nanotubes....Go to contribution page

Prof. Baoshan Xing (University of Massachusetts, USA)24/03/2009, 12:00Rapid development and expansion of nanotechnology and growing use of nano-products have raised numerous safety concerns among the public and scientific community. Potential release of nanoparticles (NPs) into the environment is predictable through point and/or non-point sources. Environmental parameters such as pH, ionic strength, and natural organic material (NOM) profoundly affect...Go to contribution page

Mr Sijie Lin (Clemson University, USA)24/03/2009, 14:15With the rapid development of nanotechnology engineered nanoparticles will eventually enter the environment. The interactions between engineered nanoparticles with naturally organic molecules, aquatic organisms, and plant species determine the fate of these nanoparticles in ecological systems and the food chain, and present vast new opportunities for multidisciplinary research. In...Go to contribution page

Prof. Olle Edholm (Royal Institute of Technology KTH, Sweden)24/03/2009, 15:30The free energy cost for creating water filled pores of different sizes in model membranes is discussed and calculated from molecular dynamics simulations. Clearly the free energy cost for creating a hydrophilic pore with the lipid head groups turned inwards towards that water is less than that for creating a hydrophobic pore with hydrocarbon towards the water. This depends, however, on...Go to contribution page
