Genomic instability is a risk to organism health detected by methods such as the comet assay (CA). It is a highly sensitive and versatile method to detect low levels of DNA damage in a wide range of cells from humans as well as from other species as compared to other methods with the same proposal. CA is a powerful DNA damage analysis tool and its applicability extends to the genotoxicity analysis of, that is, drugs and carcinogenic substances. This study analyzed papers employing CA in the Scopus database in order to assess its scientific importance, employability, and trends by evaluating: number of articles per year, total citations and per year, country of publication and their clusters, clusters of authors, most frequently abstracts terms, name of journal, affiliations, country of publication, subject area, relevant keywords compared to citation clusters, and impact factor (IF) CiteScore. It was retrieved 13,828 articles from 1990 to 2018, with a peak in 2014 and a decline from 2015 to 2018. Four author clusters from China, United States, India, and Brazil were identified, countries presenting the greatest number of publications. China presented the most recent scientific advances in the field. It was also detected nine clusters of themes, and a positive correlation between publications, citations, and the IF. There are full employability and versatility in the use of the method. Currently, there is an advance in Chinese scientific production on the subject, and there is greater use of the method on oxidative damage researches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
