This video archive was created in Sep 2012 as a part of project, "Harmonized supramolecular motility machinery and its diversity" (Representative: Osaka City University, Makoto Miyata) supported by the Ministry of Education, Culture, Sports, Science and Technology, Ministry of Education, Culture, Sports, Science and Technology, as a Grant-in-Aid for Scientific Research on Innovative Areas. During the area research, the videos related to motility were collected and posted in five categories including (1) eukaryotes, (2) prokaryotes, (3) molecules / proteins, (4) models (including explanation), and (5) others. Also, we released a corresponding smartphone application. The video archive and smartphone application were renewed as 'Biophysics Video Archive' as a part of “post-area project” in March 2018 and transferred to the Biophysical Society web site.
