Learning from the mussel, scientists create a biologically active titanium surface

Titanium is used medically in applications such as artificial joints and dental implants. While it is strong and is not harmful to tissues, the metal lacks some of the beneficial biological properties of natural tissues such as bones and natural teeth. Now, based on insights from mussels—which are able to attach themselves very tightly to even metallic surfaces due to special proteins found in their byssal threads—scientists from RIKEN have successfully attached a biologically active molecule to a titanium surface, paving the way for implants that can be more biologically beneficial.
