Abstract
A method for forming a bioactive agent spatially patterned includes providing a photocrosslinkable hydrogel that includes a photocrosslinkable base polymer, photocrosslinkable bioactive agent coupling polymer macromers, and at least one bioactive agent that couples to the photocrosslinkable bioactive agent coupling polymer macromer, an selectively exposing discrete portions of the photocrosslinkable hydrogel to actinic radiation effective to initiate cross-linking of the base polymer and the bioactive agent coupling polymer macromers at the exposed portions.
