Scientists at EPFL in Switzerland have found a way to grow dense metal structures inside a simple water-based gel, producing parts that can withstand 20 times more pressure than those made with ...

The ideal material for interfacing electronics with living tissue is soft, stretchable, and just as water-loving as the tissue itself--in short, a hydrogel. Semiconductors, the key materials for ...

Hydrogels are characterized by their hydrophilic nature and 3D network structure, possessing the unique ability to absorb significant amounts of water or biological fluids. This feature makes them ...

Growing cells in the laboratory is an art that humans have mastered decades ago. Recreating entire three-dimensional tissues is much more challenging. Researchers are developing a new hydrogel-based ...
