Analytical Chemistry Lab
Machine-translated · View original
A lab that explores how shells and bones form by looking at the interplay between organic and inorganic substances.

AboutAbout the lab
Bridging bioinorganic chemistry and analytical chemistry to understand life processes
The Analytical Chemistry Lab focuses on life phenomena involving inorganic elements, studying both the inorganic elements and the organic molecules that take part in them.
Its central goal is to elucidate the mechanisms of biomineralization, the process by which organisms build minerals, as in shells, bones, and teeth.
Building on bioinorganic chemistry and analytical chemistry, the lab investigates these questions using a wide range of analytical methods.
The lab also reframes calcification in organisms as a way of storing carbon, and aims to connect this to decarbonization technologies.
Key terms
- Biomineralization
- The process by which organisms build minerals such as shells, bones, and teeth. Also called biological mineralization.
- Organic molecule
- Molecules built on a carbon backbone. They include proteins and other molecules that are the main materials of living organisms.
- Calcification
- The formation of minerals such as calcium carbonate inside the body of an organism.

ResearchResearch themes
The lab focuses on life phenomena involving inorganic elements, studying the inorganic elements and organic molecules involved with a variety of analytical methods. In particular, it works to elucidate the mechanisms of biomineralization, the process by which organisms build minerals.
*Illustrative imageHow shells form
The lab investigates which organic molecules regulate the formation of the finely structured biominerals found in shells and bones. It has discovered new proteins involved in crystal formation from the shell of the Akoya pearl oyster.
*Illustrative imageNew analytical methods tailored to the purpose
The substances inside living organisms vary widely in type and amount, and can be difficult to analyze with standard methods. The lab develops new analytical methods tailored to each purpose, aiming to elucidate life phenomena.
*Illustrative imageFixing carbon dioxide as calcium carbonate
Calcification has long been considered a reaction that releases carbon dioxide, but recent research is leading to a reassessment. The lab aims to develop a technology that uses calcium in seawater to fix carbon dioxide as calcium carbonate.
*Illustrative imageHow organisms accumulate metals
The lab studies the mechanisms by which metals become highly concentrated inside the bodies of organisms. Its work includes searching for proteins in scallops that bind to cadmium.
