I developed STM system for application of STM-IETS measurement to a giant molecule system. The system was applied for real space imaging of DNA and denaturation of protein. Real space imaging for protein 53, known as anti-oncogene, shows polymerized state and its various features depend on its concentration. The application of STM-IETS based on the knowledge of this research will establish a new structural analysis method for a giant molecule.

为了将STM-IETS测量应用于大分子体系，我研制了STM-IETS测量系统。该系统被用于DNA的实空间成像和蛋白质的变性。对被称为抑癌基因的蛋白53的实空间成像显示了其聚合态，其各种特征取决于其浓度。基于本研究知识的STM-IETS的应用将为大分子的结构分析建立一种新的方法。
