In Vitro Endothelialization on CNx Films Deposited on PTFE
X. L. Qing,F. Z. Cui,C. L. Zheng 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.1
Endothelial cells were successfully seeded onto carbon nitride (CNx) ¯lms deposited on poly-tetra°uoroethylene (PTFE) by using the ion beam-assisted deposition (IBAD) technique. X-ray photoelectron spectroscopy and, Raman characterization of the resulting ¯lms showed that IBAD was e±cient in fabricating CNx ¯lms with controllable nitrogen content and sp2=sp3 fraction. The 48 hr cell culture indicated the endothelial cells grew best on CNx ¯lm with greatest nitrogen content. The CNx-coated PTFE may be a promising vascular prosthesis in vascular reconstruction.
