The Japanese scientists announced the development of the hydrogel, called "double network" (DN) gel and published their work in Nature Biomedical Engineering. The team, led by Prof Jun Suzuka ...

which triggers more crystal formation in the polymer network. The end result is a hydrogel with a tensile strength (withstanding stretching) of 51 Megapascals (MPa), and a compressive strength ...

Hydrogel is a 3D network that is composed of hydrophilic polymers, which can absorb and swell in water. Hydrogels can be prepared by different cross-linking strategies, and they are classified in ...
