ABSTRACT
In the period barely exceeding one year elapsed after its emergence, COVID-19 has caused more than 100 000 000 contagions and more than 2 000 000 deaths worldwide. Faced with this situation, scientists from various disciplines have arduously struggled against the disease. One of the disciplines involved in research about COVID-19 is nanomedicine, which is defined as the medical application of nanotechnology. The purpose of the study was to describe the current status of research about COVID-19 oriented nanomedicine through a bibliometric analysis. A search was conducted for Web of Science publications from the period 2019-2021, covering five nanomedicine areas: 1) drug administration, 2) drugs and therapy, 3) in vivo imaging, 4) biosensors and 5) biomaterials. The data obtained from Web of Science were processed with Bibliometrix, an open code tool programmed in R-language useful for bibliometric analysis. A total 155 publications were found, most of which were articles and literature reviews. More than 70% of the publications dealt with drug administration and biosensors. The scientific journals publishing the largest number of articles were ACS Nano, Biosensors & Bioelectronics and Nanomaterials. The countries with the largest scientific production were the United States, India and China. The most relevant contributions of nanomedicine to the struggle against COVID-19 are the development of nano vaccines and the design of nanostructured biosensors for diagnosis. © 2022, Centro Nacional de Informacion de Ciencias Medicas.
