Course description and aims

This course is for students in Tokyo Tech-Tsinghua University joint graduate program. The course is held at Tsinghua University in Beijing and mainly deals with the fundamental concepts of soft materials. Since the instructors and the topics change every year, the course contents will be revised every year. This year, the course will be divided into two: the former half will deal with single molecule spectroscopy and super-resolution microscopy and the latter half will be nanomechanics based on atomic force microscopy.


With the progress of nanoscience and nanotechnology on the one hand, and the development of organic and soft-matter based opto-electronic and bio-sensing device technology on the other, there has been an increasing interest in the characterization of the basic physical properties of soft matter on nanometer scales, as well as in the study of basic physical and chemical phenomena occurring on the level of molecules. Optical methods, and optical microscopy in particular, offer the possibility to non-invasively localize regions of interest on nanometer scales and at the same time to study many of the physical and chemical phenomena by monitoring the response of the matter to light.

The goal of the lecture is to provide the students with the background knowledge necessary to understand the methods of single molecule spectroscopy and super-resolution microscopy, and to familiarize themselves with the potential and limitations of these techniques. Further, the goal is for the students to get an overview of recent developments in the field of nanoscale photochemical and photophysical characterization and phenomena in polymer solids and soft matter.

Student learning outcomes

At the end of the course, students will acquire the following abilities:
1) Ability to explain the photochemical and photophysical characterization and phenomena in polymer solids and soft matter by single molecule spectroscopy and super-resolution microscopy
2) Ability to explain the method to measure the mechanical properties of polymers by means of atomic force microscopy.
