Nano personal protective equipment against SARS-CoV-2: Insights from a bibliometric analysis of recent publications and patents

Main Article Content
Abstract
In the context of COVID-19, which is a highly contagious disease, the use of personal protective equipment (PPE) is of great importance, both by health professionals and the community in general. As the transmission of the virus is done by inhalation or direct contact with infectious droplets, the use of PPE, especially face masks, has become the “new normal” for societies. However, to improve the filtering and elimination potential of viruses, as well as the breathability and comfort of masks, many studies have been performed in this area. This work evaluated articles and patents on the topic of nanotechnological PPE through a bibliometric analysis. Data were collected from 2016 to 2021, extracted from databases such as PubMed and Web Of Science, and analyzed using bibliometric techniques. In addition, a patent review was carried out to assess current inventions related to the protective mask. The results show that the USA produced the largest number of academic publications related to nanotechnology and personal protective equipment, and India and Brazil also stood out in the number of publications. Among the most discussed nanomaterials for association in PPE were metallic nanoparticles and nanofibers, especially silver nanoparticles. In addition, through the results, the increase in publications on the subject in recent years was highlighted, and it is believed that growth will continue indefinitely, due to the prevention of current and future pandemics.
