The effects of seawater on adhesives produced by marine mussels

Wednesday, October 31, 2018 - 16:00

paper published in the Royal Society’s journal Interface explores the effects of seawater on protein-based adhesives produced by marine mussels (bivalve mollusks). According to the study conducted by UW researchers, low pH and oxygen conditions in seawater cause the mussel’s adhesive plaques to weaken.

The work bridges the fields of marine biology and materials science, with promising findings for  many industries including biomedicine and aquaculture, that use biological systems as an inspiration for the development of new materials. A better understanding of ideal conditions for mussel adhesives can aid in the design of medical adhesive products used in wet body cavities. Aquaculture farms also rely on strong mussel attachment when the animals are cultured on ropes suspended in coastal water.

The study involved two former UW students, Matthew George and Benjamin Pedigo, as well as UW biology professor Emily Carrington. Penn Cove Shellfish of Coupeville, Washington, the oldest and largest mussel grower in the U.S., partnered in the study. The research was also conducted in association with the UW’s Friday Harbor Laboratories. George, the lead author on the paper, conducted the study as part of his dissertation research at the UW. He’s now a postdoctoral researcher at the Mayo Clinic. Pedigo served as an undergraduate researcher and is now pursuing graduate studies at Johns Hopkins University.

The Royal Society is the oldest scientific academy in continuous existence. The journal Interface explores cross-disciplinary research at the interface between the physical and life sciences.
