Hydrogel Responsive to Nitric Oxide

Caption

IBS scientists developed a hydrogel made of polymeric acrylamide (blue spaghetti) linked with crosslinkers (black), which can accommodate drug molecules (purple stars) within its mesh (grey). In the presence of nitric oxide (red), the linker is cleaved and the drug molecules can be released. At the same time, the gel absorbs fluid from the surroundings and swells in size.
