Schematic illustration of promoting wound healing process in the presence of Gel-H.P.Cur. a Thickness wound formation in the skin, and attacking of opportunistic bacteria. Due to the local inflammation and swollen, the wound starts to expand. b Treating with Gel-H.P.Cur promotes the healing processes. For instance, bacteria are prevented from entering the wound bed, and gradually the swelling and local inflammation decreases and also exudates are absorbed by the hydrogel. Proliferation of fibroblasts and angiogenesis are stimulated by both HA and curcumin. c After treatment with Gel-H.P.Cur the wounded tissue is completely regenerated and a slight scar is seen on the wound surface
