Sprayable anti-adhesive hydrogel for peritoneal macrophage scavenging in post-surgical applications.

Post-surgical adhesions frequently occur after intra-abdominal surgery, leading to severe complications. Despite the development of various types of adhesion barriers to address post-surgical adhesions, several limitations persist, including off-target localization, handling difficulties, and potential immunogenicity. Here, we report a spray-type adhesion barrier for broad, fast application, forming two sequential networks.

Mussel-inspired sulfated hyaluronan cryogel patch with antioxidant, anti-inflammatory, and drug-loading properties for multifunctional wound adhesives.

Wounds, characterized by the disruption of the continuity of body tissues resulting from external trauma, manifest in diverse types and locations. Although numerous wound dressings are available for various wound scenarios, it remains challenging to find an integrative wound dressing capable of addressing diverse wound situations. We focused on utilizing sulfated hyaluronan (sHA), known for its anti-inflammatory properties and capacity to load cationic drugs.

Recent advancements in enzyme-mediated crosslinkable hydrogels: -mimicking strategies.

Enzymes play a central role in fundamental biological processes and have been traditionally used to trigger various processes. In recent years, enzymes have been used to tune biomaterial responses and modify the chemical structures at desired sites. These chemical modifications have allowed the fabrication of various hydrogels for tissue engineering and therapeutic applications.
