Transformative Biomaterials in Burn Care: Utilizing Scaffolds, Hydrogels, and Chitosan for Optimized Healing and Scar Reduction

With over a million patients per year in the USA alone, burns are among the most common injuries in the world. In addition to preventing difficulties during burn injuries, the growing impact of scaffolds, hydrogels, cell scaffolds, and cell sheets with healing boosting elements expedite triggers and strengthens re-epithelialization and wound healing, which limits the creation of scars. While superficial partial-thickness and superficial burns typically heal without surgery, severe burns require special care, including topical antimicrobial surgery or bandages. Usually composed of polymeric biomaterials, scaffolds offer the structural support needed for cell adhesion and the subsequent formation of tissue. The term "tissue engineering triad" often refers to cells, scaffolds, and growth-stimulating signals. This may be accomplished in several ways by combining different polymers. Simple (planar) 3D structures may be produced using conventional and rapid prototyping techniques, but complicated structures have been successfully produced by carefully controlling the Molds and processing parameters. For biomedical and tissue engineering applications, chitosan has been widely employed (skin, bone, cartilage, and vascular grafts to substrates for mammalian cell culture). Additionally, it is renewable, biocompatible, biodegradable, nonantigenic, bioactive, and nontoxic.
