In 2003, Jian Ping Gong, a professor of soft and wet matter at Hokkaido University, invented what is called double-network hydrogels. In these materials, an additional harder, more brittle interior ...

Double-network hydrogels are a soft, yet tough material formed of about 85 weight percent water and two types of polymer networks: one rigid and brittle, and the other soft and stretchable.

What sets the PDN apart from other injectable double-network hydrogels is its ability to form cell-sized pores upon injection. Injectable hydrogels are desirable in many areas of regenerative medicine ...

A research team from Northwest University, China, has developed a breakthrough nano-composite hydrogel system to address the ...

Researchers have developed a life-like hydrogel cartilage that could help improve elderly mobility by ... (2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt) (PAMPS) double network hydrogel.

Their "double network" hydrogels -- formed from two intertwined molecular networks -- are mechanically strong, but highly tunable for mimicking the physical characteristics of human tissue.
