Scope Nanotoxicology invites contributions addressing research relating to the potential for human and environmental exposure, hazard and risk associated with the use and development of nano-structured materials. In this context, the term nano-structured materials has a broad definition, including ‘materials with at least one dimension in the nanometer size range’. These nanomaterials range from nanoparticles and nanomedicines, to nano-surfaces of larger materials and composite materials. The range of nanomaterials in use and under development is extremely diverse, so this journal includes a range of materials generated for purposeful delivery into the body (food, medicines, diagnostics and prosthetics), to consumer products (e.g. paints, cosmetics, electronics and clothing), and particles designed for environmental applications (e.g. remediation). It is the nano-size range if these materials which unifies them and defines the scope of Nanotoxicology . While the term ‘toxicology’ indicates risk, the journal Nanotoxicology also aims to encompass studies that enhance safety during the production, use and disposal of nanomaterials. Well-controlled studies demonstrating a lack of exposure, hazard or risk associated with nanomaterials, or studies aiming to improve biocompatibility are welcomed and encouraged, as such studies will lead to an advancement of nanotechnology. Furthermore, many nanoparticles are developed with the intention to improve human health (e.g. antimicrobial agents), and again, such articles are encouraged. In order to promote quality, Nanotoxicology will prioritise publications that have demonstrated characterisation of the nanomaterials investigated.

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Total Cites 

Evolution of the total number of citations and journal's self-citations received by a journal's published documents during the three previous years.
Journal Self-citation is defined as the number of citation from a journal citing article to articles published by the same journal.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
