The cell is the smallest unit of life. Cells have been cultured outside of animals' bodies and used in various biological
experiments and diagnostics, and production of protein and other valuable biomolecules. Cells can be also a promising candidate
of a part of biosensing devices that will detect complex and combination of biomolecules at high sensitivity that could not
be realized with any human-made devices.
However, since single cells easily die, degrade, and require strict physicochemical conditions to our knowledge in animal cell culture, utilization of cells in the engineering contexts needs more breakthrough in handling cells that is possible in methods of engineering. Not only knowledge in behavior and mechanism of cells, but also various engineering viewpoints and approaches needs to be acquired to develop "easy-to-use" cell devices. These engineering approaches include establishing the system to maintain the cell health and the physicochemical conditions (surface properties, media, atmosphere, flow, concentration gradient), in appropriate ranges, building the system to maintain cells in a simple, biologically sterile and reproducible methods, and the system to obtain signals and information from the cells inside.

Students will study the topics that will be fundamental to utilize cells in a engineer-friendly ways. These topics will be
selected mainly from the fields of biomaterials, animal cell culture, and microfluidics.
Students will study the method of English literature search and how to read journal articles through preparation of mini-reports and the final presentation.

- Students should understand the physicochemical principles and conditions that is relevant and/or can be defined in the cell environment.
- Students should understand the methods of cellular assays in biology and other life sciences．
- Students should understand the methods to engineer environment/atmosphere suitable to cell cultivation as "a device".
