The blue mussel attaches itself to rocks using very strong water-based glue that is water-resistant. As glues are usually synthetic or toxic, mimicking the glue mussels use to attach themselves to rocky surfaces has tremendous potential for decreasing pollution.
Columbia Forest Products (US) has mimicked the natural mussel glue to produce PureBond® plywood that is used in toxic-free furniture.
Elsewhere, Korean scientists at Pohang University of Science and Technology (POSTECH) have looked at medical applications. The proteins in the mussel inspired glue are compatible with the human body. This has interesting applications in surgery, as it reduces the need to use staples or sutures.
