VEGF-binding peptide ligands are incorporated into hydrogel microspheres and reduce the amount of growth factor in solution. VEGF binding affinity is enhanced by creating ligands with a dimer structure. The spheres are able to knock down VEGF-mediated HUVEC growth and reduce calcium signaling. The binding interaction is reversible, allowing the spheres to be used as a VEGF delivery vehicle.
