Gelatin crosslinking
WebAs gelatin is highly soluble in aqueous medium, we crosslinked electrospun gelatin nanofibers using saturated GTA vapor to increase the water resistive properties. For controlled release over a period of 12 h, we devised several strategies to vary the crosslinking conditions and accordingly understand their effect on drug release … WebPhotoinitiated crosslinks can be formed in situ to control hydrogel stiffness and gelation rate and fabricated with varying degrees of crosslinking content under ultraviolet (UV) or visible light. Minimally invasive photocrosslinkable hydrogels are ideal for 3D cell culture and TE applications, providing exceptional temporal and spatial control.
