Application

Silk is a natural polymer composed of two proteins - fibroin and sericin. Silk fibroin has been widely used in biomedical applications due to its biocompatibility and biodegradability. Silk Methacryloyl (SilMA) is produced by methacrylation of silk fibroin using glycidyl methacrylate. The hydrogels prepared using SilMA possesse superior mechanical strength and rheological properties, which make them ideal for tissue engineering applications. SilMA can be used for bioink formulation. And SilMA bioinks are suitable for use in digital light processing (DLP) based 3D bioprinting to develop functional tissue constructs.
