Functionalization of CoCr surfaces with cell adhesive peptides to promote HUVECs adhesion and proliferation
(Applied Surface Science, 2017)Biomimetic surface modification with peptides that have specific cell-binding moieties is a promising approach to improve endothelialization of metal-based stents. In this study, we functionalized CoCr ... -
Cell adhesive peptides functionalized on CoCr alloy stimulate endothelialization and prevent thrombogenesis and restenosis
(Journal of biomedical materials research. Part A, 2017)Immobilization of bioactive peptide sequences on CoCr surfaces is an effective route to improve endothelialization, which is of great interest for cardiovascular stents. In this work, we explored the ... -
Chitosan-recombinamer layer-by-layer coatings for multifunctional implants
(International Journal of Molecular Sciences, 2017)The main clinical problems for dental implants are (1) formation of biofilm around the implant—a condition known as peri-implantitis and (2) inadequate bone formation around the implant—lack of ... -
