Millimeter-scale hydrogels form reversible, stimulus-responsive assemblies that encode high-density data, offering a dynamic alternative to static printed codes for adaptive information storage.

Flexible electronics have been drawing significant attention for healthcare applications and show great promise for monitoring of blood circulation (e.g., postoperative monitoring of free flaps).

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 ...

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 ...

A cube of healthy bone is anything but solid. Inside it, countless tiny channels carry fluid and help cells move, feed, and rebuild. Xiao-Hua Qin, a professor of biomaterials engineering at ETH Zurich ...

Inspired by biology, researchers have achieved the highest performing underwater adhesive hydrogel technology to date through a data mining and machine learning approach. Hydrogels are a permeable ...

Researchers from the Institute of Polymer Science and Engineering, National Taiwan University, have developed a smart gel that responds to multiple stimuli for precise drug release. Gels that respond ...

view from top of jar with yogurt isolated on white background. Eat yogurt spoon close up. Researchers used yogurt by-products to create extracellular vesicles and then used the vesicles to make a ...

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 ...
