Bombyx mori silkworms weave a cocoon by secreting a substance from their glands at the final stage of larval development. This secretion consists of fibroin and sericin proteins. Fibroin, which forms the thread part, is a soft, white, and shiny fiber composed of two chains: a heavy chain and a light chain connected by disulfide bonds, and is a glycoprotein.
Fibroin, a protein in fiber form, stands out due to its exceptional material properties, biocompatibility, biodegradability, high durability, and ease of processing. Thanks to its biocompatibility, biodegradability, and applicability, it is considered a notable bioactive material for tissue engineering applications. It is used in the production of 3D scaffolds combined with various materials (natural or synthetic polymers, drugs, nanoparticles, growth factors, bioactive molecules, etc.) that support wound healing. In addition, silk fibroin has been utilized in various in-vivo studies for applications involving the brain, soft tissue, subcutaneous tissue, and bone. The silk fibroin protein is widely applied in cell culture studies, wound dressings, drug delivery, enzyme immobilization, and scaffolds in bone/tissue engineering. Silk fibroin is a durable, lightweight, and flexible material. Due to its unique physical and chemical properties, it can be used in numerous industrial and medical applications.
