Biomimetic nanocomposite hydrogel networks for robust wet adhesion to tissues

Designing multifunctional medical adhesives with strong adhesiveness under water is of great significance to achieve desirable therapeutic effects for promoting wound healing. However, its design is still challenging since most of existing hydrogel adhesive cannot work in wet environments. Here we proposed a tissue adhesive made from a combination of hydrogel matrix and nanocrystal fillers. The adhesion mechanism of this hydrogel adhesive relies...
