Abstract: Nanotechnology is a cornerstone of the scientific advances witnessed over the past few
years. Nanotechnology applications are extensively broad, and an overview of the main trends
worldwide can give an insight into the most researched areas and gaps to be covered. This document
presents an overview of the trend topics of the three leading countries studying in this area, as
well as Brazil for comparison. The data mining was made from the Scopus database and analyzed
using the VOSviewer and Voyant Tools software. More than 44.000 indexed articles published
from 2010 to 2020 revealed that the countries responsible for the highest number of published articles
are The United States, China, and India, while Brazil is in the fifteenth position. Thematic
global networks revealed that the standing-out research topics are health science, energy,
wastewater treatment, and electronics. In a temporal observation, the primary topics of research are:
India (2020), which was devoted to facing SARS-COV 2; Brazil (2019), which is developing promising
strategies to combat cancer; China (2018), whit research on nanomedicine and triboelectric
nanogenerators; the United States (2017) and the Global tendencies (2018) are also related to the
development of triboelectric nanogenerators. The collected data are available on GitHub. This study
demonstrates the innovative use of data-mining technologies to gain a comprehensive understanding
of nanotechnology's contributions and trends and highlights the diverse priorities of nations in
this cutting-edge field.
