Review of superresolution fluorescence microscopy to observe nano-scale objects by Prof. Katsumasa Fujita is published in  Manufacturing & Technology (SEISAN TO GIJYUTU), 2015 Summer (in Japanese). Some methods were awarded Nobel prize in Chemistry last year. SAX invented by Prof. Fujita has been introduced in this home page. R&D of widely available and high performance superresolution fluorescence microscopy is expected to advance science and technology in various fields such as biology, medical and material.
