Abstract: With the wide application of nano-technology in the field of biology,nanobiotechnology as a new subject is formed. The studies on nano-drug carrier and nano-traditional Chinese medicine have been one of research hotspots in the field of biological pharmacy in recent years. The definition of nano-technology and nanobiotechnology were summarized. The related research progresses on nano-drug carrier and nano-traditional Chinese medicine were introduced in detail,so as to provide theoretical basis for further application of this technology.
