[www.ferro-alloys.com]Inspired by the mussel’s ability to very tightly attach itself to even metallic surfaces using unique proteins found in its byssal threads, a team of researchers from RIKEN have managed to attach a biologically active molecule to a titanium surface. This achievement is likely to open doors for implants that can be more biologically beneficial.

Titanium has been used in medical applications such as dental implants and artificial joints. Although titanium is not harmful to tissues and strong, it lacks certain of the beneficial biological properties of natural tissues such as natural teeth and bones.

The researchers’ work is based on former discoveries that mussels have the capacity to attach themselves to smooth surfaces because of a protein called as L-DOPA. It is known that this protein can strongly attach to smooth surfaces such as ceramics, rocks, or metals.

The same protein acts as a precursor to dopamine in humans. It is also used as a treatment for Parkinson’s disease.
