Course description and aims

This course is organized into four parts. The first part of the course deals with an AFM (atomic force microscopy). The AFM has become a powerful tool to study biological samples not only for imaging at the molecular level but also for measuring their mechanical properties. The course begins with an overview of AFM and then goes to applications of AFM to the study of the biological materials. The second part introduces nuclear magnetic resonance (NMR) spectroscopy. The third part describes the vibrational spectroscopy. It includes quantum chemical description of molecular vibrations, normal modes, principle and setup of infrared spectroscopy and Raman scattering, and their examples of several important molecules such as benzenes. The vibrational relaxation will also be shown with examples. The fourth part deals with a super-resolution microscopy (SRM) using 2-color laser spectroscopy. Due to the diffraction of light, the resolution of conventional laser (light) microscopy is limited, and is almost the same as a wavelength of light. The lecture begins with the principles of SRM beyond the diffraction limit by using 2-color laser spectroscopy, and then goes to the applications of SRM to the observation of biological samples including living cells.

Class flow

The class starts with reviews of previous class. Towards the end of class, students are often given exercise problems related to the lecture given that day to solve. To prepare for the class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside the classroom for preparation and review purposes.
