Polymer gel is a three-dimensional polymer network in a liquid. When a water is the dispersion medium water inside its network structure, the gel is referred to as a polymer hydrogel. Since the hydrogel contains a large amount of water, it has excellent characteristics such as external stimulus responsiveness, shock absorbability, low friction, and biocompatibility which are difficult to obtain in general solid materials. Owing to the similarity between hydrogels and soft tissues, many studies are in progress for tissue engineering and regenerative medicine. Recently, some researches on the application of hydrogels as wound dressings have attracted much attention. Conventional wound dressings show some disadvantages in that inflammation occurs or additional devices are required by using incompatible materials in vivo. While improving these things, the biocompatible tissue adhesives using natural polymers were investigated on the toxicity and the adhesive behavior in this study. |
