To make improvement of hemocompatibility on the titanium (Ti) substrate, mussel-inspired adhesive polymer (PMDP) with both catechol groups for surface anchoring and phosphorylcholine groups for obtaining biocompatibility was synthesized. Only 10 s-immersion of Ti substrate into an aqueous solution of PMDP resulted in reliable coating, because the coating was stable during one month rinsing. The PMDP-coated Ti substrate showed significant reduction of amount of proteins and number of platelets adhered on the surface compared with the non-treated Ti substrate. For this immobilization method, no chemical pretreatment of the substrates is necessary, and a stable and hemocompatible coating can be prepared by a simple, one-step procedure. Thus, we concluded that the proposed PMDP immobilization method has promising approach for improving hemocompatibility of Ti substrate for cardiovascular implant application. (C) 2012 Elsevier B. V.
