Fabrication of photo-crosslinkable glycol chitosan hydrogel as a tissue adhesive

In this work, an in situ gelling system composed of glycol chitosan (GC) was fabricated and evaluated regarding its tissue-adhesive, anti-bacterial and hemostatic properties. GC conjugated with 3-(4-hydroxyphenyl) propionic acid gelled immediately after illumination with blue light in the presence of ruthenium complex. The phenolic GC hydrogel was investigated regarding its mechanical property, hydration, degradation rate, cytotoxicity, tissue...
