A Reloadable Self‐Healing Hydrogel Enabling Diffusive Transport of C‐Dots Across Gel–Gel Interface for Scavenging Reactive Oxygen Species

While reloadable drug delivery platforms are highly prized for the treatment of a broad spectrum of diseases, the gel–gel interface between hydrogels hinders the intergel diffusive transport of drugs and thus limits the application of hydrogels as reloadable depots. Here, this study reports the circumvention of this barrier by employing a self‐healing hydrogel prepared from N ‐carboxyethyl chitosan and sodium alginate dialdehyde, which are...
