General description

Silk is a natural polymer composed of two proteins - fibroin and sericin.
Silk fibroin is used in biomedical applications due to its enhanced biocompatibility and biodegradability.

Silk fibroin (SF) demonstrates enhanced strength and stability compared to other common natural polymers due to its unique features including;
  • amphiphilicity
  • hydrophobicity
  • substantial hydrogen bonding
  • intrinsic low viscosity
  • high protein crystallinity by ß-sheet crystals.

Application

SF is a versatile material, that finds itself in multiple types of scaffolds, with extensive uses in inkjet, extrusion-based, laser-assisted, and DLP bioprinting tissue engineering applications.
