Research Article: Procedural Promotion of Wound Healing by Graphene-Barium Titanate Nanosystem with White Light Irradiation

Date Published: 2023-08-07

Abstract:
Skin is the largest organ of our body, and as the first immune barrier, it protects the body from pathogens at all times. Skin is also vulnerable to various threats, and skin damage and wound formation are common in response to external detrimental stimuli. Wound healing is a complex dynamic process that compromises multiple stages including hemostasis, inflammation, multiplication and remodeling.– After skin damage, the hemostasis phase occurs immediately, aiming to quickly stop bleeding. Hemostasis is caused by blood vessel constriction and platelet accumulation and coagulation at the vascular wound and to form a protective barrier to prevent external pathogens entering the bloodstream. Inflammation phase is the secondary stage of wound healing. In this phase, the wound is susceptible to bacterial infection, which may lead to inefficient healing. The immune system is activated in this phase to trigger inflammation aiming to inhibit bacterial growth and wound infection, thus accelerating the process of wound healing. Multiplication phase is the third stage of wound healing and is the key step in wound healing. In this phase, endothelial cells and other cells such as fibroblasts and epidermal cells proliferate and migrate to form new blood vessels and new tissues gradually covering the wound. Remodeling phase is the fourth stage of wound healing, wound is completely closed and new epithelium and scar are formed in this phase. Wound healing requires that all stages are coordinated, and if any stage is not carried out normally, it will lead to delay of the healing process.
