Surface Modification of Silk Fibroin with PEG for Use as Anti-Adhesion Barriers and Anti-Thrombotic Materials
Researchers at Tufts University have developed novel silk biomaterials that are surface-modified with polyethylene glycol (PEG). These materials have utility in various biomedical applications where cell adhesion or thrombosis must be controlled. The degree of PEGylation on each surface can be varied to tune the properties of the silk biomaterials.Background...
