Brown University researchers have shown a way to use graphene oxide (GO) to add some backbone to hydrogel materials made from alginate, a natural material derived from seaweed that's currently used in ...

Flexible pressure sensors can detect subtle mechanical stimuli, making them suitable for use in wearable sensors for human ...

Cut and mixed with water to make a thick gel. Diluted with more water and filtered. Mixture evaporated and further processed to make sodium alginate powder.

The temporary structures, which can be degraded away with a biocompatible chemical trigger, could be useful in fabricating microfluidic devices, creating biomaterials that respond dynamically to ...

Hydrogels, soft materials consisting of polymer and water, could replace damaged cartilage in people or serve as artificial muscles and nerves for soft, deformable robots. But it’s difficult to make ...
