Graphite has been widely used in various fields since ancient times because of its excellent thermal, mechanical, electrical, and chemical properties. 2004, Geim et al. at the University of Manchester isolated a layer of graphene (0.3 nm thick) and showed interesting properties. Since then, the research on graphene has been expanding worldwide. In this seminar, we will introduce a chemical method to obtain graphene quickly and in large quantities, which is suitable for future device applications, and its features.

　Many of you may know that the cover of the entrance examination guide for the Department of Advanced Life Sciences has remained unchanged since 1998, when the first entrance examination was held, and has always been designed with a baby on it. However, it is a little known fact that the baby's mitochondria are inherited only from the mother. Even if you have heard that mitochondria and chloroplasts are maternally inherited, many of you may not know how this happens. In this article, we will discuss our research on maternal inheritance to answer the question, "Why? In this article, we will introduce some of our research that answers the "why?" questions surrounding maternal inheritance, and also explore the background to the evolution of large eggs, small sperm, and only two sexes: male and female. 　

　The research and development of chemical sensors is progressing, and electronic devices that can operate in a wet environment are becoming widely used. Here, we introduce an attempt to culture nerve cells on a substrate with integrated microelectrodes and observe their behavior as a group. We are also working on the measurement of myocardial activity, which has the same electrical activity as the nervous system, as well as applications in regenerative medicine.
