Abstract
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.
