Scope
Aims, scope and focus
Free Radical Research is published by Informa Healthcare and is in Zone 3 of Biology in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Antioxidant Activity and Oxidative Stress, Free Radicals and Antioxidants and Nitric Oxide and Endothelin Effects, together about 28.9% of its articles. Its main subfields are Biochemistry and Molecular Biology. (generated from OpenAlex topic counts and CAS ranking data)
Free Radical Research aims to publish high-quality research papers, hypotheses and reviews in all areas in the fields of: • Free radicals and other reactive species in biological, clinical, environmental and other systems • Redox signalling • Antioxidants, including diet-derived antioxidants and other relevant aspects of human nutrition • Oxidative damage, mechanisms and measurement Manuscripts should contribute a significant advance to the field, supported by clearly-presented data and statistical analysis. Manuscripts should be as concise as possible subject to the need to present relevant background, data and methods. Reviewers are strongly encouraged to identify areas of the manuscript that could be shortened. FRR discourages papers that are purely descriptive (e.g. a catalogue of changes in antioxidant levels in a human disease or after administering a toxin to an animal). We also discourage ‘screening’ papers, such as the use of ‘total antioxidant activity’ assays to compare the antioxidant activities of plant extracts or herbal medicines including traditional medicines.
