Combined Endothelialization Promoting And Surface Binding Chimeric Conjugate With Low Thrombogenicity
BIOCONJUGATE CHEMISTRY(2021)
Abstract
Endothelialization of blood contacting implants, e.g., vascular stents, is regarded as a prerequisite for an improved performance in terms of minimizing thrombogenicity and the inhibition of restenosis. Commonly used materials, such as Ti-based alloys, can be surface-modified in order to improve endothelial cell (EC) colonization as well as to reduce platelet adhesion. Standard modification techniques involve silanization and are laborious and time-consuming. We propose a novel single-step procedure based on a surface-recognizing peptide generated by phage display methodology. Combining this with a polyethylene glycol (PEG) spacer and an EC-specific sequence yielded a conjugate applicable for the modification of Ti surfaces.
