Research on the bio-safety of nanomaterials

With the rapid development of nanotechnology, nanometer material is used more and more widely. The contact of human beings, animals, plants and nanometer materials has become inevitable. This paper summarizes the progress of biologic security research of a variety of typical carbon nanometer material metals and oxide nanomaterial and semiconductor (insulators), including fullerenes (C60), single-walled carbon nanotubes muIti-walled carbon nanotubes, gold, iron oxide, alumina oxide: zinc oxide, titanium dioxide, silica, zinc sulfide, zinc selenide. This paper also analyzes the existing difficulties and problems during the research of biological safety of nanomaterial, and makes an outlook of the future development of the research on biological safety of nanomaterial as well.
