Abstract:
By utilizing multicolor upconversion luminescence of rare earth-doped nanophosphors (UCNPs), NIR-light-activated photopolymerization and controlled drug delivery is achieved for PEGDA hydrogels. The loading capacity of zinc(II) phthalocyanine reaches 12.3% into UCNPs-PEGDA hybrid microspheres.
