This paper deals with nanoethics as a sort of extension of engineering ethics utilizing various books, articles, and reports concerning historical, social, and ethical aspects of nanotechnology. After a brief examination on the place and development process of nanotechnology, ethical issues on nanotechnology are analysed including safety problem, impact on environment, violating privacy, social inequity, military use, and human enhancement. The basic principles on nanoethics are proposed such as promotion of public understanding, construction of participatory governance, contribution to sustainable development, commitment to precautionary principle, and compliance with research integrity. Lastly, integrated method in nanoethics education is illustrated putting lecture model, investigation model and discussion model together. This paper can provide the contents available for nanoethics education, and make a basis for the sound development of nanotechnology.
