Abstract
Halloysite nanotube (HNTs) is a new natural aluminosilicate nanometer material.It has many advantages,such as unique nano-tubular structure,high specific surface area,and high reactivity.In recent years,HNTs has had more and more important applications in the field of biomedical transport.In this paper,the structure and properties of HNTs were briefly introduced.The feasibility of HNTs application in biomedical field was analyzed.The researches and applications of HNTs in enzyme immobilization,biological imaging,biological scaffold,targeted transport of cytotoxic drugs and gene,and other aspects of the application,were illustrated emphatically.Compared with traditional inorganic nanomaterials,HNTs has many advantages in the field of biomedical applications such as good immobilization effect,easy chemical modification,high biocompatibility,low toxicity,and high selectivity.Finally,the challenges of the HNTs in the field of biomedicine were pointed out,including long medical results conversion cycle,high medical costs,and unexplained drug release mechanism.The prospects of the HNTs in a series of modem medical technologies,such as disease diagnosis,targeted delivery of drugs and follow-up treatment,were also discussed.关键词
