The lab is an analytical chemistry lab that develops separation and measurement methods based on new principles.
AboutAbout the lab
New Principles, New Frontiers in Analytical Chemistry
The Analytical Chemistry Lab develops separation and measurement methods based on new principles, with the aim of opening new frontiers in analytical chemistry.
In living organisms and the environment, most molecules exist as aggregates or microparticles, and the major reactions take place at interfaces.
The lab aims to develop microspectroscopy to study these interfacial reactions and methods that use electric and magnetic fields to separate microparticles one by one, and to establish methods for investigating the structure of chiral molecules.
Key terms
- liquid-liquid interface
- The boundary where two immiscible liquids, such as water and oil, meet. Here it refers to a region a few nanometers thick.
- chirality
- The property of a molecule whose shape cannot be superimposed on its mirror image. It is often likened to the relationship between the right and left hands.
- Raman optical activity
- A technique that measures chirality by using molecular vibrations as a clue.
ResearchResearch themes
The lab aims to develop separation and measurement methods based on new principles and to open new frontiers in analytical chemistry. Its research covers reactions at liquid-liquid interfaces, separation and property measurement of microparticles, and structural analysis of chiral molecules.
*Illustrative imageStudying Liquid-Liquid Interface Reactions with Microspectroscopy
To elucidate the heterogeneous reactions that occur specifically at liquid-liquid interfaces only a few nanometers thick, the lab develops measurement methods that combine optical microscopy and spectroscopy. It works on the analysis of metal complex aggregates and the measurement of the permeation rate of substances across the interface.
*Illustrative imageSeparating Microparticles with Electric and Magnetic Fields
Targeting nano- to micrometer-sized particles such as DNA, proteins, and cells, the lab develops analytical methods that use the minute forces exerted by electric and magnetic fields to separate individual particles one by one and measure their properties. It is advancing magneto-optical microscopic analysis using pulsed magnetic fields and separation analysis by magnetophoresis.
*Illustrative imageProbing Chiral Molecular Structure Through Vibrations
Aiming to establish methods for analyzing the flexible chiral higher-order structure of proteins and the absolute configuration of chiral drug molecules, the lab studies Raman optical activity, which measures chirality at vibrational levels. It also works on structural analysis of chiral molecules in solution and on quantum mechanical calculations that reproduce the vibrational spectra of polymers.
