Journal of Biophotonics

Journal of Biophotonics is the first international journal dedicated to publishing original articles and reviews from the exciting field of biophotonics, i.e. the development and application of photonic technologies in particular for (bio)medicine, but also life- and environmental sciences. The journal offers a platform where technology developers (physicists, chemists, engineers, etc.) communicate with endusers (in particular research clinicians) and where the clinical practitioner learns about the latest tools for the diagnosis and therapy of diseases. As such, the journal is highly interdisciplinary, publishing innovative research in the field of light interaction with biological material. The coverage extends from fundamental research to specific developments, while also including the latest applications or clinical trials/case reports.

SJR

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.
