Researchers create new 'smart' material with potential biomedical, environmental uses

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 a variety of biomedical applications. In a paper published in the journal Carbon, the researchers describe a 3-D printing method for making intricate and durable alginate-GO structures that are far stiffer and more fracture resistant that alginate alone.
