Facile and versatile solid state surface modification of silk fibroin membranes using click chemistry†
Abstract
Reported is a fast and versatile protocol to surface modify pre-cast silk membranes targeting tyrosine residues. Enriched alkyne silk membranes were prepared using this method and azides possessing a range of functional groups were tethered to the membrane surface using click chemistry to give a range of water contact angles from 85 ± 3° to 34 ± 6°.
