Abstract/OtherAbstract:
|
Telechelic poly(n-butyl methacrylate)s (PBMAs) with various end groups were prepared using nonionic, anionic, cationic or zwitterionic azo-type radical initiators and cell adhesion onto the surfaces of the polymers was investigated. The tendency for cell adhesion to the polymers differed with and without pretreatment with phosphate-buffered saline (PBS, pH 7.4). The cell adhesion to polymer surfaces without pretreatment was lower than that with pretreatment. The effect of pretreatment with PBS was significant for PBMA with ionic end groups. Furthermore, cell adhesion to the surface of PBMA with zwitterionic end groups was suppressed compared with that to the surfaces of other polymers. It was presumed that positive and negative charges of zwitterionic groups in the same molecule negated each other at pH 7.4 and that the polymers with zwitterionic end groups had no effective charges. The results clearly indicated that biocompatibility of polymers can be changed by the introduction of functional groups at the ends of the polymer chains. Fabrication of functional material surfaces will be anticipated by the similar method in the future. |
