Alginate-GO (IMAGE) Brown University Caption Brown University researchers have created a hybrid material out of seaweed-derived alginate and the nanomaterial graphene oxide. The 3-D printing technique used to make the material enables the creation of intricate structures, including the one above, which mimics that atomic lattice a graphene.
