Biodegradable hydrogels cross-linked with hyaluronic acid serve as inflammation-sensing systems. At sites of inflammation leukocytes and macrophages produce hydroxyl radicals, which specifically break down the hyaluronic acid cross-linking, thus aiding in drug release at the site of inflammation.47 48...
