Almost always when you see large ships. they’re are painted red at the waterline and below and these are what are called antifouling paints and so what they do is they keep the shellfish from sticking or fouling to the ships. The way they work is they leach copper ions into the water around the ship and so when the shellfish are in their larval state they can’t handle the large amounts of copper in the water and so they die and they don’t stick. So what our approaches is rather than just killing the animals, it’s look at how the animals are actually making the adhesive and then try to shut down that chemistry without killing the animals. So what we’ve been able to do is form these surfaces or these coatings that have antioxidants in them and we put mussels on them and we’ve measured their adhesion, and sure enough what we’re finding is that the adhesion of the mussels to the surfaces drops significantly when the antioxidants are present.
