BACKGROUND
Silver nanoparticles (AgNPs) have been widely applied in research and industrial fields, finding applications in nanomedicine, drug delivery, biomedical devices, electronics, the energy sector, and environmental protection. Patents provide information on the industrial viability of product technologies, and the number of patent documents provides an estimate of the evolution of a specific technological field.
AIMS
The present work aims to describe the current trends in AgNPs patent applications. In addition, a retrospective study of published patents in Brazil is presented.
METHODS
Analyses of AgNPs-related patents were conducted using the free platform for patent search Lens® in 2010-2019 and articles published in same period using the Scholar® base. The patent applications and their evolution over time, major depositors and holders, and the main technological areas associated with AgNP applications have been described.
RESULTS
China and United States are the major patent applicants for nanotechnologies. The worldwide distribution of publications of journal articles shows that China, India, and the United States are the leading countries in the total number of articles published, in that order.
CONCLUSION
Our study of patent applications and published articles confirmed the growing global increase in new technologies involving NPs and AgNPs, particularly in the biotechnology area, in the fields of medicine and agriculture.
背景
银纳米粒子（AgNPs）已广泛应用于研究和工业领域，在纳米医学、药物输送、生物医学设备、电子、能源和环境保护等领域得到了应用。专利提供了产品技术工业可行性的信息，专利文献的数量可以估计特定技术领域的发展情况。
目的
本研究旨在描述 AgNPs 专利申请的现状。此外，还对巴西已发表专利进行了回顾性研究。
方法
使用免费的专利搜索平台 Lens®对 2010-2019 年 AgNPs 相关专利进行分析，并使用 Scholar®数据库对同期发表的文章进行分析。描述了专利申请及其随时间的演变、主要申请人和持有者，以及与 AgNP 应用相关的主要技术领域。
结果
中国和美国是纳米技术的主要专利申请人。期刊文章发表的全球分布显示，中国、印度和美国是发表文章总数最多的国家，依次排列。
结论
我们对专利申请和已发表文章的研究证实了涉及 NPs 和 AgNPs 的新技术在全球范围内的增长，特别是在生物技术领域，在医学和农业领域。
