Overview of Research and Education

The National Institute for Materials Science (NIMS) and the Graduate School of Life Science of the Hokkaido University have established a joint Doctoral Program in the Field of Frontier Biomaterials Science. The laboratory is located in NIMS in Tsukuba city, Ibaraki.
When pathogens infect us, our cells recognize DNA or RNA molecules of bacteria and viruses and the immune system is activated. With attention to this biological immune system, we are developing nucleic acid-based nanomedical molecules, and also nanoparticle-conjugated nanomedicines, and applying these to the treatment of infectious diseases and allergies.
