The lab uses channels thinner than a human hair to capture information for chemistry, biotechnology, and medicine.
AboutAbout the lab
Useful information for society, from the narrowest channels
The Mawatari Lab studies micro/nanofluidic devices carved with channels thinner than a human hair.
Chemical, biological, and medical analysis requires handling liquids, and it has been difficult to make devices from which information can be easily extracted.
The lab therefore combines devices, measurement and analysis, and information technology to build systems that capture information about the environment, food, viruses, and blood.
It also works on fundamental research on liquids in nanospace and on single-cell analysis, carrying out interdisciplinary research that spans chemistry, biotechnology, mechanical engineering, and electrical engineering.
Key terms
- Micro/nanofluidic device
- A device that studies liquids by flowing them through channels thinner than a human hair carved into a small plate
- Nanospace
- An extremely small space only about 100 nanometers deep or wide
- Single-cell analysis
- A method of examining the properties of individual cells, rather than measuring many cells together

ResearchResearch themes
Advanced devices that make it easy to obtain information are essential for the development of an information society. The Mawatari Lab combines micro/nanofluidic devices, measurement and analysis, and information technology, aiming to realize ICT for chemistry, biotechnology, and medicine and to put it to use in society.
*Illustrative imageAnalysis and diagnostic devices
The lab combines analysis and diagnostic technologies for the environment, biotechnology, and health with micro/nanofluidic devices. Its projects include a portable instrument for measuring heavy metals in river water, low-cost gas sensors, and water sampling by drone.
*Illustrative imageSemiconductors and microfluidics
Bringing micro/nanofluidic technology into the semiconductor field, the lab researches devices for cooling semiconductors, aimed at next-generation 3D chiplets.
*Illustrative imageAI, devices, and data
The lab combines machine learning with data obtained from devices. Its targets include volume control of concentration devices, non-invasive methods for measuring flow and pressure, fluid control from the cloud, and mapping of environmental pollution.
*Illustrative imageScience of liquids in nanospace
The lab investigates how water and solutions behave in channels only about 100 nanometers wide. Its topics include capillary action in nanochannels, and proton diffusion and enzymatic reactions in channels that mimic biological systems.
