Biofunctional Polymers Lab
Machine-translated · View original
A lab that creates materials for medicine and the environment from the mechanisms by which biopolymers assemble themselves.

AboutAbout the lab
Opening up the potential of life through polymers.
The Biofunctional Polymers Lab studies how to understand and design self-assembly, the process by which biopolymers gather on their own to form structures.
From there, its research extends to biomembrane engineering, nanomedicine, and environmentally responsive materials.
Working across polymer chemistry and life science, the lab aims to understand life phenomena and to apply that understanding to medicine and the environment.
Key terms
- Self-assembly
- The process by which molecules gather on their own to form an ordered structure without being assembled from outside
- Extracellular vesicles
- Tiny membrane-enclosed sacs that cells release to the outside. They are involved in the exchange of information between cells
- Nanomedicine
- Medical technology that uses materials on the nanometer scale to deliver drugs or treat the body
