The mussel glue probably uses both mechanical and chemical bonds, said Messersmith. Other materials can stick to Teflon, notes Messersmith, but the process is expensive and complicated. Messersmith's method is faster and easier. "We dip [a material] into the solution, let it sit, and the primer spontaneously adsorbs to the material." Antibiotic silver nanoparticles were also added to the primer to create a bacteria-killing surface. Silver nanoparticles have been used for years in products to eliminate odors caused by microscopic creatures, though recent research has suggested the nanoparticles may pose an environmental hazard. While the new glue may help advance pharmaceuticals and antibacterial coatings, their freshwater models have a less helpful reputation. They are known for causing millions of dollars of damage each year by sticking to everything from water intakes to boat hulls. In a nod toward their new technology's inspiration, the researchers named their company Nerites. Nerites, according to Greek mythology, was a titan who was turned into a mussel as punishment.
