Outline of Final Research Achievements

We have synthesized the first cationic radical initiator (ADIP) and prepared non-toxic cationic fluorescent nanogel thermometers. By using the new nanogel thermometers, long-term monitoring of intracellular temperature can be performed. In addition, the effects of maturation of brown adipocytes on their thermogenesis were investigated. The contribution of pannexin-1 on the thermogenesis was also elucidated.
