Flexible agar-sericin hydrogel film dressing for chronic wounds

Chronic wounds suffer impaired healing that results in psychological effect and morbity in addition to economic burden on the patient. These wounds are characterized by prolonged inflammatory phase, poor collagen production, hampered angiogenesis, upregulation in reactive oxygen species (ROS) and matrix metalloproteases (MMP). In the current work, three different concentrations (03:01, 05:01 and 10:01) of flexible agar-sericin-glycerol hydrogel...
