Control of dynamics of molecules and molecular systems is extremely important to create novel functions in materials and biological systems. The use of light along with application of electric field as a tool to give external stimuli has many advantages which originate from the characteristics of interaction among photon, molecules and electric field.

    

分子和分子系統動力學的控制對於在材料和生物系統中創建新功能極為重要。光的使用以及將電場作為施加外部刺激的工具具有許多優點,這些優點源自光子,分子和電場之間相互作用的特性。

    N. Ohta has completed his PhD from Tohoku University, Sendai, Japan, and postdoctoral studies from Marquette University in Milwaukee, USA. Until March 2015, he was Professor at Hokkaido University, Sapporo, Japan. He is now Chair Professor at National Yang Ming Chiao Tung University, Hsinchu, Taiwan and Professor Emeritus at Hokkaido University.

    He is interesting in electric field effects on structure, dynamics, and function of photoexcited molecules and molecular systems including optoelectronic materials, molecular conductors, ionic conductors, and living cells. He has focused to the Photoelectric and Photobioelelctric Research, where novel materials functions and novel biological function are quested by photoirradiation and application of electric field. In the materials research, electroabsorption and electrophotoluminescence spectra, i.e., electric field effects on absorption and photoluminescence spectra, time-resolved photoluminescence decay with and without application of electric field and time-resolved photocurrent have been measured. In the research of biological system, he has focused on autofluorescence lifetime microscopy to examine intracellular function and its ultrashort pulsed electric field effect with special attention to the difference between non-malignant normal cells and cancerous cells.

太田信廣 講座教授

太田信廣教授在日本仙台東北大學獲得博士學位,以及美國Marquette University in Milwaukee進行博士後研究。

太田信廣教授擔任日本札幌北海道大學的教授至2015年3月,他現在任職於國立陽明交通大學,也同時是北海道的名譽教授。

教授致力於電場對結構、動力學和功能的影響,光激發分子和分子系統,包括光電材料,分子導體,離子導體和活細胞。他專注於光電和光生物電學研究,新型材料在其中光輻射和電的應用尋求新的生物學功能領域。在材料研究中,電吸收光譜和電致發光光譜即電場對吸收和光致發光光譜的影響,時間分辨在不施加電場和時間的情況下發生光致發光衰減測量了分辨的光電流。在生物系統研究中,他有專注於自發熒光壽命顯微鏡檢查細胞內功能和其超短脈衝電場效應,尤其要注意兩者之間的區別非惡性正常細胞和癌細胞。
