Nanomaterial

Nanotechnologies make use of very small objects or artifacts. Nano-materials are an increasingly important product of nanotechnologies. They contain nanoparticles, smaller than 100 nanometers in at least one dimension. Nano-materials are coming into use in healthcare, electronics, cosmetics, and other areas. Their physical and chemical properties often differ from those of bulk materials, so they call for specialized risk assessment. This needs to cover health risks to workers and consumers, and potential risks to the environment. This is currently done on a case by case basis, but risk assessment methods need to be kept up to date as the use of Nano-materials expands, especially as they find their way into consumer products. What do we know about the possible health risks of exposure to the nanomaterial, and how can assessment of these risks be improved?
