RIKEN Center for Advanced Photonics Live Cell Super-Resolution Imaging Research Team
Team Leader: Katsumi Midorikawa (D.Eng.)
Research Summary
Light is a cutting-edge tool for life science research. Development of useful fluorescent probes and the advancement of light microscope technologies have brought us a new world of “live” imaging within a cell. We are developing super-resolution confocal live imaging microscopy (SCLIM) by the combination of a high-speed confocal scanner and a high-sensitivity camera system. With this method we will observe membrane trafficking and organellar dynamics in living cells at high-speed and super-resolution (4D) and elucidate underlining molecular mechanisms. We will also try to extend this technology to medical and pharmacological applications.
