Scientific knowledge about ultrafine bubbles obtained so far has been explained for supporting the promotion of international standardization of fine bubble technology (ISO/TC281). The mechanism of the ultrafine bubble generation, the long-time duration of its existence, various useful effects has been explained based on the obtained scientific experimental and analytical results, which would not be enough so far. The expected industrial applications and the important fundamental research topics of ultrafine bubbles have been described based on the several characteristic features of ultrafine bubbles.
