Nanotechnology is believed to have a number of different and significant impacts in terms of social, economic, national and environmental security. Nanotechnological innovations and breakthroughs may lead to a loss of a number of jobs. Liquid crystal displays that are manufactured using nanotechnology will much likely make contemporary methods of making conventional television obsolete. However, nanotechnology is also expected to make new jobs available.
Human health care advancements made possible by nanotechnology based techniques, procedures and materials are also expected. A ten year increase in the expectancy of human life around the world could also be expected. Nanotechnology can be used to improve assessment, diagnosis and treatment techniques and methods. Nanotechnological advancements can likewise be used in prevention and or reversal of congenital diseases and hereditary conditions.
Nanotechnology can be used to quickly and safely heal potentially fatal wounds and prevent incidences of infection and tissue or organ loss. Cancer could be made a thing of the past by using nanotechnology to destroy cancer cells immediately after its diagnosis. Nanotechnology and nanomaterials also pose a number of adverse environmental effects.
Proper regulation of nanotechnology based materials should be put in place to minimize any harmful environmental effects. Nanomaterials are invisible to the naked human eye, therefore extra care and caution should be taken to avoid unnecessary release of these extremely minute particles into the atmosphere.
Nonetheless, a wide majority of nanotechnology based products and devices will be composed of nanomaterials that are joined together with other materials or components rather than free floating very minute objects, which will therefore not pose such a great risk. However, nanotechnology can help in producing materials and substances that can help in reducing carbon emissions, clean up air and water pollutants and aid in removing air and water borne toxins and pathogens among others.
The great surface areas of nanomaterials give them a significant ability and capacity to adsorb and absorb dangerous and potentially deadly chemicals. Ultimately, nanotechnology is expected to significantly improve security and defense. Efforts to prevent biochemical weapons and its effects can be improved by nanotechnology. Similarly, monitoring and surveillance can also be enhanced by innovations made by the field.
