The lab uses polymer nanomaterials to measure and control what happens inside cells.

AboutAbout the lab
Opening up unexplored life science through the power of materials.
The Unregistered Lab uses polymer nanomaterials to study how to "measure" phenomena occurring inside cells and how to "control" cell functions.
The lab puts forward a new research concept called "Materials-Initiated Biology," which opens up unexplored life science through the power of materials.
It also works on mechanobiology, which examines the forces generated between materials and cells, and on the study of biological phase separation using nanomaterials.
Key terms
- Polymer nanomaterials
- Polymer materials that the lab designs as tools for measuring and controlling cells
- Mechanobiology
- The field that studies the forces generated between materials and cells
- Single-cell level
- Handling cells one by one, distinguishing each individual cell

ResearchResearch themes
The lab seeks to understand how cells receive stimuli from their external environment and how cell function changes as a result. It aims to regulate cell functions with polymer nanomaterials and to observe life phenomena that are not yet known.
*Illustrative imageMeasuring cells with polymer nanomaterials
Taking advantage of the properties of polymer nanomaterials, the lab develops new bioanalytical techniques that can contribute to advances in medicine and life science. It takes on the analysis of phenomena and samples that have been difficult to detect or observe until now.
*Illustrative imageMaterials that control cell functions
The lab designs polymer nanomaterials that can deliver heat or mechanical stimulation in response to near-infrared light or magnetic fields. It works on creating techniques to control function at the single-cell level without damaging the cells.
