Recent applications of the Comet Assay: A report from the International Comet Assay Workshop 2019

The International Comet Assay Workshops (ICAW) are a series of scientific conferences dealing with different aspects of the comet assay. The assay itself is a simple method for the detection of DNA strand breaks at the cellular level and can be applied to any cell type derived from different organs and tissues of eukaryotic organisms. Additionally, the comet assay is widely applied in human biomonitoring, ecotoxicology, genotoxicity testing of chemicals, but also in basic research studying the mechanisms of DNA damage and repair. The 2019 ICAW edition gathered about 80 participants with over 30 lecturers, 27 poster presentations and 2 open discussion sessions presenting the latest advances in technical developments as well as applications of the comet assay in genetic toxicology, and environmental and human biomonitoring. This report summarises the important issues that were raised and discussed during the sessions as well as a short synopsis of the papers selected for inclusion in this special issue. Based on the topics presented at the workshop, the assay with its new modifications and applications has a bright future and will for sure stay one of the most popular methods in genetic toxicology and beyond in the years to come.
