Biomaterials play a crucial role in tissue engineering, serving as scaffolds, matrices, or carriers for cells, growth factors, and other bioactive molecules. Natural biomaterials like collagen and chitosan, synthetic biomaterials like PLA and PGA, and hybrid biomaterials are used in tissue engineering. These biomaterials provide a three-dimensional structure for cell growth, tissue regeneration, and drug delivery. They must possess properties like biocompatibility, biodegradability, and suitable mechanical properties to match the tissue they intend to replace or repair.
