RESUMO
Nanotechnology, as a newly arisen technology, does not only benefit people, but also become one of the inevitable threats to public health due to the widely application of nanomaterials. The safety evaluation of nanomaterials has become one of the hottest research topics in the 21st century, which provides opportunities and challenges in the field of preventive medicine once in a blue moon. Although the history of development in the safety assessment of nanomaterials is just over twenty years, the achievements could not be underestimated. This paper summarized the research of nano biological, predicted the directions for future research, and proposed several recommendations, based on which, we hope it can promote the sustainable development safety in China.
