Simulations reveal role of calcium in titanium implant acceptance

Titanium-based materials are widely used in medical implant technology, and coating the surface of titanium materials with biologically active molecules has recently shown promise to improve how cells adhere to implants. The mechanisms behind how peptides stick to titanium, however, are not fully understood. Researchers have now found how calcium ions present at the interface between titanium oxide and tissues affect how well peptides bind to the metal. The team reports their findings in Biointerphases.
