Building on supramolecular chemistry, the lab creates materials that open the way to a sustainable future.

AboutAbout the lab
Bringing out the full potential of molecular functions
The Aida Lab researches new materials based on “supramolecules,” which form when molecules assemble through weak forces.
Its goal is to connect new molecules and materials to solutions for real-world problems in areas such as energy and medicine.
In addition to knowledge of organic chemistry and molecular assemblies, the lab draws on ideas from photochemistry and electrochemistry. It also learns a great deal from the functions of living organisms.
The lab at Hongo Campus began as an endowed chair funded by Kao Corporation, and it also conducts basic research that leads to products such as hair care and skin care.
Key terms
- Supramolecule
- An assembly in which multiple molecules are held together by weak forces. Its properties change depending on how the molecules assemble.
- Supramolecular polymer
- A long chain of small molecules (monomers) linked by dynamic bonds that can be reconnected.
- Organelle
- A small structure inside a cell that carries out a specific function. Mitochondria are an example.
- Endowed chair
- A research and education unit established at a university with donations from companies or other organizations.

Based on “supramolecular chemistry,” the lab is pioneering materials science that makes a sustainable future possible, as well as basic science for a safe and secure society. Its laboratories are located at Hongo Campus and RIKEN.
*Illustrative imagePioneering and Applying Supramolecular Polymers
The lab was a pioneer in developing supramolecular polymers, in which monomers are linked by dynamic bonds. Its results include polymer glasses that self-heal at room temperature and supramolecular plastics that are metabolized in seawater.
*Illustrative imageSupramolecular Chemistry Inside Cells
Using peptides designed on chemical principles, the lab creates artificial droplets and organelles inside cells, aiming to open a new frontier in cell engineering.
*Illustrative imageDelivering Drugs with Molecular Machines
Using molecular machines found in living organisms, among other tools, the lab is developing smart drug carriers that deliver a drug to the right place at the right time, in response to substances that a disease produces in the body.
*Illustrative imageRapidly Separating Nucleic Acids That Differ Only Slightly
Rapidly separating DNA or RNA that differ by only a single nucleotide is important for nucleic acid therapeutics, but it is extremely difficult. The lab discovered that this can be done with ammonium sulfate and a glass plate, and it aims to extend the method to protein separation and practical use.
