Professor Cha Hyung Joon (CE) and his research team became the world’s first team to discover how mussels strongly adhere to the surface through dopa-iron ionic bond and pH. Until this discovery researchers were not sure how the adhesion worked.
The team used the properties of dopa, a very important amino acid in mussel’s adhesion. Dopa bond strongly with each other. The team researched how dopa-iron bonds and pH influence cohesiveness and adhesion. In the beginning, adhesive strength has a bigger influence and at the end, cohesiveness does. The team revealed that an increase in pH leads to stronger adhesion.
Prof. Cha said, “This research provided clues on understanding mussel’s adhesion mechanism by investigating dopa-iron ionic bond. It is also expected to bring application in biobinding agent.”
