Ethical Issues in the Application of Nanotechnology

Nanotechnology is the science and manipulation of matter in the range of 1-100 nm. This technology has the potential for improving human life and rapid medical and economic growth. This technology is applied for manufacture of carbon nanotubes, drug delivery, medical diagnosis and treatment of diseases.Nanotechnology raises a variety of ethical concerns such as questions concerning risks to human beings and the environment and access to the technology. Because nanomaterials, by definition, have novel properties, they may affect animals and humans in unpredictable ways. It also raises a concern about entrance nanomaterial via dermal, oral and respiratory system. Since the risks of human exposure to nanomaterials have not been well studied at this time, it is necessary to consider preventive and cautionary proceedings in the use of these materials.
