Because of their size, nanomaterials can have drastically different properties than their corresponding bulk (normal/not nanoscale) materials. These altered features can impart very desirable properties, including being less expensive, harder, and generally more efficient in particular industrial applications. Due to their increased use, exposure to nanomaterials is also expected to increase. With this exposure, there is a risk that the specific properties of nanomaterials could cause them to have adverse biological effects, such as toxicity and genotoxicity, which are different from their bulk counterparts. For example, while the bulk counterparts may be inert, the surface properties of some nanomaterials may lead to the formation of reactive oxygen species, that in turn may produce cellular damage, DNA adducts, and genotoxicity [2].
