摘　　要：主要介绍了新型星状金纳米晶的研究进展,介绍了其主要的制备工艺,阐述了星状金纳米晶在药物运载与释放、催化、及SERS增强方面的显著应用;同时简略介绍了一些其他贵金属星状纳米晶的应用性能。制备中通过添加不同贵金属晶种、还原剂与表面活性剂,控制[金属盐溶液浓度]/[晶种数目]的摩尔比,调节星状纳米晶尖端长度与数目;同时对不同贵金属星状纳米晶的应用前景进行了展望。The paper gives a brief review of a new nanocrystalline morphology - Au nanostar. The main processes of the preparation of Au nanostars was introduced. The applications of Au nanostars were elaborated, including drug carrier and release, catalytic and SERS enhancements. At the same time, applications of some other noble metals nanostars were describes briefly. By adding different kinds of noble metal seeds, the reducing agent and surfactants and adjusting the molar ratio of [ salt concentrations ]/[ number of seeds ],the number of tips and its lengths can be changed to control. At last, the existing problems of nanostars and improvement measures are proposed.
