The lab uses polymer nanofilms to measure and treat the body.

AboutAbout the lab
Where nano, bio, and electronics meet.
The Fujie Lab builds new diagnostic and therapeutic technologies on a foundation of polymer nanofilms.
Nanosheets, tens to hundreds of nanometers thick, are exceptionally flexible and adhere directly to living tissue.
Key topics are nanobiomaterials, tissue engineering, cell therapy, and wearable and implantable devices.
By combining materials, electronic circuits, and living tissue, the lab aims to develop technologies that benefit human health.
Key terms
- Nanosheet
- A thin polymer film tens to hundreds of nanometers thick. It is soft and adheres physically to living tissue
- Tissue engineering
- Technology that combines cells and materials to build body tissue artificially
- Implantable device
- A device implanted in the body that measures biological signals or acts on the body

ResearchResearch themes
Building on polymer nanofilm technology, the lab develops nano- and micro-scale technologies for diagnosing and treating intractable diseases. Its research combines polymer materials, molecular assemblies, tissue engineering, bioelectronics, and bioinspired engineering.
*Illustrative imageNanobiomaterials
Using polymer nanosheet technology, the lab developed the "nano-plaster," the world's thinnest wound dressing. Its thickness ranges from tens to hundreds of nanometers and its area can be varied from micrometers to meters. It shows exceptional flexibility and physical adhesion to living tissue.
*Illustrative imageTissue engineering and cell therapy
Using microfabrication, the lab makes ultrathin scaffolds that mimic the fine structure of the extracellular matrix, and uses them to assemble living tissue. By designing material surfaces, it aims to guide how cells align, for example so that muscle fibers line up in one direction.
*Illustrative imageWearable and implantable technologies
The lab develops "printed nanofilms," in which conductive materials, sensors, and electronic components are placed on nanosheets. They can measure biosignals such as myoelectric potential, body temperature, and pH, and can also deliver light wirelessly to an affected area for photodynamic therapy.
