The comb-like PEG (CPEG) end-tethered with l-lysine was explored to surface modification of PET to enhance endothelialization. The hydroxyl end groups of CPEG were oxygenated into aldehyde groups. The CPEG-CHO was grafted onto the aminolysized PET. The l-lysine was then end-tethered onto surface via the residual aldehyde groups. The surface modification was confirmed by ATR-FTIR, contact angle and XPS measurements. The endothelial cell adhesion, proliferation and viability results indicated… CONTINUE READING
