Abstract
Visible light-induced cross-linkable chitosan was synthesized by the incorporation of furfuryl isocyanate. The synthesized chitosan derivative was analyzed by 1H NMR and GPC. The synthesized chitosan derivative showed no significant toxicity. The synthesized chitosan derivative was mixed with Rose Bengal in distilled water and irradiated with visible light for 5 min in the presence of a photomask. A micropattern that matched the micropattern of photomask was formed and the photoreactivity of the synthesized chitosan derivative was confirmed. Solidification of the synthesized chitosan is believed to have occurred by a photo-oxidation-induced cross-linking mechanism. Contact angle measurements and cell culture on the surface of solidified chitosan derivative were also carried out. Cell adhesion on the surface of solidified chitosan was not shown. Considering these results, the synthesized chitosan derivative is non-cytotoxic, solidifies rapidly by visible light not chemicals, and has fewer cell interactions. The synthesized chitosan derivative is a novel candidate for anti-adhesive agent.
