In the field of biomedical nanotechnology, chitosan and alginate —both naturally derived biopolymers — have garnered significant attention due to their ...

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.
