摘　　要：该文基于德温特专利数据库,利用TDA、Thomson Innovation等分析工具或平台对1980-2011年纳米药物领域专利进行了分析,系统揭示了30多年以来纳米药物的研发现状、技术热点以及技术分布与格局。研究发现纳米药物领域相关专利的申请数量呈现出逐年增长的态势,特别是2000年后专利申请数量呈现出明显加快的趋势;纳米药物领域专利主要集中在:超音速喷雾干燥技术、药物靶向递送、共聚物药物、多肽、抗原、树枝状大分子等方向。In order to show the development status of nanodrug technology, the analysis of patent literature during 1980-2011 （data from Derwent Innovations Index of ISI WoK） is carried out by using analysis tools TDA and Thomson Innovation. The status of research and development of nanodrug in the 30 years, hot spots, as well as the technical distribution pattern were revealed. The study found that the number of related patents in the field of nanodrug application showing a growth trend year by year, especially after 2000, showing a significantly accelerated trend; patents in the field are mainly concentrated in Supersonicjet Spray Drying, Drug Targeting Delivery, Copolymer Drug, Peptide, Antigen, Dendrimers, etc.
