Research Abstract	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.
