Study on carbon nanotubes（CNTs） as drug carriers and their safety were introduced in this review.Recent evidence suggests that with the cross development of biology and material science

researchers realized that applications of new drug carriers are crucial to the research of drugs.Due to their unique structure

CNTs can be used as drug carriers to build unique drug delivery system.In some rare cases

functionalized CNTs with good solubility and low toxicity show good perspective in used as drug carriers.However

research of CNTs be used as drug carriers（especially traditional Chinese medicine） is rarely reported at home and abroad.Study on CNTs as carriers（adriamycin

epirubicin hydrochloride

dexamethasone

amphotericin B and Isoliquiritigenin

etc.） and its toxicity（tissue toxicity and cell toxicity） is summarized.Emerging studies suggest that application of traditional Chinese medicine as drug carriers is attractive.We hope to provide reference for the development of safe

controlled and efficacious new drug carriers and clinical treatment of related diseases.
