The Toxicity of Nanomaterials Dissertation Example | Topics and Well Written Essays - 1000 words

The Toxicity of Nanomaterials - Dissertation Example In this regard I would indicate that nanotechnology is an activity that involves manipulation measurement, modeling or manufacture of a sub-100 nanometer while nanomaterials are nanomaterials are materials identified to be of one dimension (Powell & Kanarek 2006, 16). Effects and Toxicity of Nanomaterials Nanotoxicology is an analysis of toxicity of nanomaterials. As a result of the many uses acquired from nanomaterials it has been argued that since nanomaterials are beneficial, the properties can be toxic and dangerous to the cell environment of an organism. This therefore proves that such behavior of properties can easily react with the body tissues which may cause harm and damage of body organs, such as the brain. When such substances are inhaled and enter the internal human organs such as the heart and the lungs, they are likely to cause breathing difficulties in an individual. This shows that nanomaterials have toxins that may be harmful to the life of an organism. The high leve l of surface to volume ratio of atoms to react with other available orgasms suggests that these nanomaterials can react ferociously with the body tissues which would lead to a wear and tear of the body. This would lead to several effects in the body that can make the body to stop functioning as a result of this technology. For example, apart from the damage identified in the brain, the fish had a change in their livers which signified a physiological difference as an influence of fullerenes. A similar study was conducted by the National Institute for Environmental Studies in Japan by a researcher Shosaku Kashiwada. The main objective of this study was to investigate the risks of nanomaterials on organisms. Fish was used as a specimen in this study which showed results that the fish had accumulated nanomaterials in their gills intestine and the bloodstream. This has raised worries with the increase of nanomaterials around the globe indicating the need of safety for workers and users. In addition, researchers in Swedish Karolinka institute conducted a study that gave an indication that iron oxide showed DNA damage on the human body. It has been identified that industries have taken much interest in this technology where they have used the nanomaterials in cosmetics. These cosmetics have been used by humans who apply them on their skins, but are thereafter is able to penetrate to the inner tissues of the body (Powell & Kanarek 2006, 17). Nano sized titanium dioxide is a good example because it has properties that enable it to sunscreen when exposed to sunbeams that lead to the activation of oxidation which causes much harm to the DNA in human beings. The above information indicates that nanomaterials have toxic properties that are dangerous to the health and surrounding of an organism. The paper indicates that titanium dioxide has been applied in several fields of human life such as the making of tooth paste, plastics and pharmaceutical products. This has been as a result of its property of being transparent which has contributed in making the factory and consumer items attractive and beautiful. This indicates that the nanoscale objects have posed much danger to
