Nano/Micro Analytical Chemistry Lab
Machine-translated · View original
A lab that measures chemical phenomena in tiny nano- and micro-scale spaces.

AboutAbout the lab
Measuring the chemistry that takes place in tiny spaces
The Nano/Micro Analytical Chemistry Lab studies chemical phenomena that occur in tiny spaces on the scale of nanometers and micrometers, as well as analytical chemistry that makes use of those spaces.
The lab fabricates its own experimental devices by microfabrication and handles minute amounts of liquid and tiny water droplets.
Its work includes analyzing the process by which proteins form fibrils, bioanalysis using tiny water droplets, and developing portable analytical instruments.
On the lab's website, it is presented under the name “Hibara Lab.”
Key terms
- Microfluidic device
- A small device in which fine channels and tiny chambers are made on a substrate, so that chemical operations and analysis can be performed with small amounts of liquid.
- Spontaneous emulsification
- An emulsification phenomenon in which tiny droplets form naturally at the interface where liquids meet, without vigorous stirring.
- Immunoassay
- An analytical method that uses the property of antibodies binding to specific substances to measure substances contained in samples such as serum.

ResearchResearch themes
The lab studies chemical phenomena that occur in tiny spaces on the scale of nanometers and micrometers, as well as analytical chemistry that uses those spaces. By elucidating solution chemistry and interfacial chemistry in tiny spaces and developing new analytical methods, it aims to establish microspace chemistry as an academic discipline.
*Illustrative imageAnalysis of nucleation in protein fibril formation
The lab studies nucleation, the first step in the formation of protein fibrils, which are important for understanding diseases such as Alzheimer's disease. Using microfluidic devices to run many experiments at the same time, it has developed a method to detect individual nucleation events.
*Illustrative imageBioanalysis using micro water droplets
The lab works on techniques that manipulate tiny water droplets formed in oil inside microfluidic devices and use them for chemical and biological analysis. It has developed a new sample pretreatment procedure that uses a phenomenon called spontaneous emulsification.
*Illustrative imageDevelopment of a portable immunoassay device
The lab is developing an easy-to-operate portable device that combines fluorescence polarization immunoassay with a microfluidic device, in collaboration with Hokkaido University, Tokyo Institute of Technology, Tianma Japan, Ltd., and Komatsu University. It can measure biomarkers and other substances in human serum within 30 minutes.
