概要 Specific binding of antimicrobial peptides to titanium (Ti) surfaces may serve to prevent biofilm formation, leading to a reduction in peri-implantitis. This study evaluated the binding behavior of conjugated molecules consisting of antimicrobial and hexapeptidic Ti-binding peptides (minTBP-1) using the quartz crystal microbalance (QCM-D) technique, and investigated the effect of modification of Ti surfaces with these peptides on the bioactivity of Porphyromonas gingivalis. Four kinds of peptide were prepared: histatin 5 (DSHAKRHHGYKRKFHEKHHSHRGY), minTBP-1 + histatin 5 (RKLPDAPDSHAKRHHGYKRKFHEKHHSHRGY), lactoferricin (FQWQRNMRKVR), and minTBP-1 + lactoferricin (RKLPDAPGGFQWQRNMRKVR). The QCM-D analysis demonstrated that significantly larger increases in peptide adsorption were observed in the conjugated peptides than in antimicrobial peptides alone.
