Created by Prof. Hyung Joon Cha and colleagues at Korea's Pohang University of Science and Technology (POSTECH), it's a hydrogel made up of alginate (derived from algae), a bioengineered mussel ...
The general applicability of the system is demonstrated with the creation of layered hydrogels from both chitosan and alginate, which are cationic and anionic polyelectrolytes, respectively.

To solve this problem, researchers designed a hydrogel coating using calcium alginate and chitosan, which is loaded with an anti-inflammatory drug called dexamethasone sodium phosphate.
